2. Can the Wharfedale DVD750/DVD750S play Region 1 DVDs?


Yes, all models of the Wharfedale DVD750 have a remote control 'hack' which allows the playback of American Region 1 DVD films.



To date, we do not have a confirmed hack for the Wharfedale DVD-M5.






2.1 - Can the Wharfedale DVD750/DVD750S play DVDs from other regions?


Yes, all Wharfedake DVD players have a remote control 'hack' which allows the playback of DVDs in any region.








2.2 What is the hack for the Wharfedale DVD750?


Every generation of the Wharfedale DVD750 players are easily hacked for multi-region playback. The following sequence of key presses on the remote control should remove region restrictions:


  • Open the drawer
  • Press 0, 1, 2, 3, Play in sequence on the remote control


The disc drawer can obscure the Infra-Red sensor when open, so ensure that you compensate for this when entereing the hack.



You can also return the player to Region 2 only mode using the following sequence:



  • Open the drawer
  • Press ZOOM
  • Press RETURN
  • Press POWER







2.3 What is the hack for the Wharfedale DVD750S?


De-regionalising a First Generation Wharfedale DVD750S can be done in one of two ways. The first removes all region restrictions, the second allows the user to specify a particular region.



Hack 1


  • Open the drawer
  • Press ZOOM
  • Press A->B
  • Press the UP CURSOR
  • Press the LEFT CURSOR
  • Press the DOWN CURSOR
  • Press the RIGHT CURSOR


Hack 2


  • Open the drawer
  • Press 1 four times
  • Press the number corresponding to the Region you wish to set the player to


The Second Generation Wharfedale DVD750S has a different hack for both Multi-Region and specific region playback. Multi-Region playback is enabled as follows:


  • Press Step
  • Press Previous
  • Press Next


To set a Second Generation Wharfedale DVD750S back to Region 2, enter the following:


  • Press Slow
  • Press Previous
  • Press Next


Finally, to set the Second Generation Wharfedale DVD750S to a specific region, enter the following:


  • Press 0, 7, 5, 0
  • Press the number corresponding to the Region you wish to set the player to








2.4 What is the hack for the Wharfedale DVD-M5?


In order to enable the Wharfedale M5 for multi-region playback, do the following:
  • Remove any discs and press 'Set up' on the remote control
  • Enter the code '62836' and then press 'Enter'
  • This should bring you to a loophole screen
  • Select 'Bypass' for multi-region and press 'Enter'
  • Press 'Set up' again to leave








3. Can the Wharfedale DVD750 cope with RCE-enabled discs?


Yes and No! With the DVD750, there are two ways of finding out - and one involves using a screwdriver! The first option is to get hold of an RCE disc - the Region 1 release of 'The Patriot' is RCE encoded. The other option is to remove the case of your player and to check the firmware version.



Follow the steps below:



  • Remove the screws and top cover.
  • Locate the firmware chip - it will be marked: Wharfedale 750 CS=nnnn (where nnnn is one of the firmware versions below):

    • 5EE8 - Original firmware, does not play RCE discs
    • CBE8 - Interim firmware, plays back RCE discs using the standard DVD750 hack
    • 328C - Latest firmware, plays back RCE discs using the standard DVD750 hack



The Wharfedale DVD750S (both Generations) and Wharfedale DVD-M5 can play back RCE discs without any problems.







4. I can't play certain Region 2 discs on my player. What can I do?


Some discs are known to cause problems with the First Generation Wharfedale DVD750. These problems can range from non-functional menus to complete refusal to play certain discs (Jaws being an example).



It is possible to 'trick' the player into playing these problem discs by using the Goto Title function of the player - this enables you to skip the menus altogether and go to the main feature or extras with relative ease.



Tesco are now offering upgrades which fix the problems with the First Generation machine. Contact them on 0845 6012549 for further information - it is not yet known whether the newest firmware for the Wharfedale DVD750 is one that supports the playback or RCE discs. Officially, this upgrade ONLY fixes the Jaws problems and as such you must own a copy of this disc in order to demonstrate the problem to a Tesco engineer, and also so they can test the player once the upgrade has been carried out.



The upgrade does NOT convert a standard DVD750 into a DVD750S - they are inherently different players. The upgrade installs the same firmware as is in the Second and Third Generation machines.






4.1 How do I play Jaws on my original Wharfedale DVD750?


By using the 'Goto Title' function on your remote control. Below is a list of titles for this particular disc:


  • 01 - The Movie
  • 23 - Photo Gallery
  • 24 - The Making of Jaws
  • 25 - Movie Trailer
  • 26 - TV trailer
  • 27 - Re-release trailer
  • 28 - Deleted Scenes
  • 29 - Out-takes


The firmware upgrade offered by Tesco fixes the Jaws problem.






4.2 I can't play the extras on the Region 2 release of Gladiator


This is a known problem with machines featuring the LSI Logic chipset. The disc has been repressed so if you can't play the Gladiator extras just send your disc back to the address below for a replacement:
Mail Marketing/CTHV
FREEPOST MID 18904
PO BOX 380
Nottingham
NG7 3ZU







5 - Can I record to VHS through the Wharfedale DVD750?


No. There is no known way of removing the Macrovision copy protection with any iteration of the DVD750 or DVD750S without resorting to a hardware/software modification.









6 - What advantages does the Wharfedale DVD750S have over the original DVD750?


  • Better remote control
  • Specific region selection
  • New bug-free firmware
  • MP3 playback
  • HDCD compatibility
  • RCE compatibility
  • Official DTS support
  • Conversion from NTSC to PAL60, PAL60R, PAL50
  • Faster in operation
  • Improved setup menus









7 - My Wharfedale DVD750S is jerky when playing back NTSC material. Is this avoidable?


There are a number of reasons for jerky NTSC playback. As standard, the Wharfedale DVD750S is set up to play back in PAL mode - this can introduce problems. Changing the output format to 'Auto' cures this problem.



Another reason for jerkiness on NTSC discs is 3:2 pulldown. This is a problem which affects 99% of players on the market and is due to the way 24fps film is converted for 30fps NTSC playback. There is no way around this problem, but for the most part it is not noticeable.










8 - Where can I buy a Wharfedale DVD750?


Tesco are the sole official supplier of Wharfedale DVD750 DVD players. There no longer appear to be any stock problems with the original Wharfedale DVD750 and most major stores appear to be able to supply them at this time.



The Wharfedale DVD750S is in rather short supply in comparison at the moment - most stores may have one or two players available. Tesco On-line should have stocks of the Wharfedale DVD750S if you cannot locate on in their main stores.










9 - What chipset does the DVD750 use?


The DVD 750 is based around the LSI Logic L64021 Mpeg decoder chip and the Hitachi SH-2 microcontroller (SH7043) (details here).



The Eprom is an SGS Thompson UV Eraseable 256K*16 40 Pin Ceramic DIL package 100ns access time and commercial temperature spec. (M27C4002-10F1)



To convert the CCIR601 digital output of the Mpeg decoder to analogue video it uses the Analog Devices ADV7170 which features 10 bit DACs and can output either RGB or S Video at the same time as composite. It also implements the macrovision protection (details here).



The DVD 750S is apparently based on the Zoran Vaddis chipset. More details on this will be added as soon as we have them.

10 - Dolby Digital 5.1 discs don't sound correct on my Pro-Logic system.


It has been reported that downconversion of a Dolby Digital 5.1 soundtrack is problematic on some versions of the Wharfedale DVD750. The problem is that DD5.1 tracks are not routed correctly to the surround speakers - this can be demonstrated with a suitable set-up disc.



When sound is passed to the surround speakers, it is output in both rear speakers (correct) as well as the corresponding front speaker for the soundchannel in question. So, if a DD5.1 sound is sent to the rear-right speaker, once downconverted to Pro-Logic it will be output from both the rear-right and rear-left speakers and also the front-right. This is mirrored with the left surround channel.



There is no known solution to this problem, and it is not known exactly which players are affected. If a disc offers a 2.0 channel track then choose this when playing the film.
