mitchy at 06:50pm on 24/04/2012 under techie helpI'm having major problems playing DVDs on my computer, but only film dvds. Playback is fine at first but after about five minutes the playback becomes choppy and rapidly degenerates until it is unwatchable. I've updated every single driver I can think of, I'm using the latest version of DirectX, I've got the latest K-lite codec pack installed and the DVDs appear to be in good condition, no major scratches or flaws. I do not have any problems with other types of video playback - mp4 and avi files are just fine. And, weirdly, I haven't had any problems watching DVDs of TV shows, just films. The problem exists across all the media players I have on my PC.
I'm running Windows XP which has been regularly updated. I'm currently triple checking for viruses and unwanted spyware but I have done this before and nothing improved. Graphics card is NVIDIA GeForce G11, sound card is RealTek Audio.
Any ideas guys? I've about reached the point where I'm thinking it's gotta be the DVD drive being freaky and I'll just buy another one. :P

doccy has walked me through a few things, like deleting a spare Primary IDE Channel that seemed to be redundant, tweaking the Registry, making sure DMA was being used, deleting some recent windows updates to see if they caused the problem etc. So far no joy. I have been able to play some DVDs successfully but not all. I can't find the common denominator. *sighs*

First thing to do:
Go to Start/ Settings/ Control Panel/ System/ Device Manager/ IDE ATA/ATAPI Controllers/ Primary IDE Channel/ Advanced Settings.
Look under Device 0, and it should be set to "DMA if available." If it says "PIO only" instead, change it, click OK, save settings, and reboot. If that doesn't work, then follow what I say in my next reply *s* Just making 2 posts so the instructions don't get mixed up ;)

Click Start, go to Run, type in REGEDIT and click OK. Navigate to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\
{4D36E96A-E325-11CE-BFC1-08002BE10318} (make sure you match the key exactly, as there may be many similar surrounding it).
Expand this key/folder and you'll notice a number of subkeys, numbered 0000, 0001, 0002, and so on. There may only be a couple, though there could be several. Click on each one and look for the item "DriverDesc" in the right pane, and to the right of that, find the ones that say "Primary IDE Channel" and "Secondary IDE Channel." If it says anything other than that, you are in the wrong subkey.
Once you identify the Primary IDE Channel key, scroll down in the right pane till you find MasterIdDataCheckSum and/or SlaveIdDataCheckSum. If you know for sure whether the drive you need to fix is set to Master or Slave, delete the appropriate key (MasterIdDataCheckSum for Master, SlaveIdDataCheckSum for Slave). If you don't have any idea, it can't really hurt to delete both. Windows will simply re-identify this information on the next reboot.
And that should fix it if the first thing hasn't.
If it hasn't fixed it, theeen... I'll look for more stuffs. But, if it has, then I'll be posting a thankyou over at this article, because it had the best laid-out walkthrough of the two methods I could find to fix it *g*

OK, first of all, should I be worried that under ATAPI controllers, I have 2 Primary IDE channels (and 2 Secondary and 2 Standard Dual Channel)?
Also, I checked the properties for both Primary IDE channels and the settings are different. Both Device 0 are set for DMA if available though, but one has Current Transfer Mode as "Not Available", and the other has CTM as "Ultra DMA Mode 6" Would this be affecting anything?

Shouldn't be a worry - I assume that you have more than one drive (DVD and CD, or somesuch?). Even if you don't, that could be a leftover from an older piece of hardware - and that might be something to come back to if these two don't have any effect :)
one has Current Transfer Mode as "Not Available", and the other has CTM as "Ultra DMA Mode 6" Would this be affecting anything?
It's the "DMA if available" that's most important - the remaining settings should be fine. And, seeing as you're on the "DMA if available" already, then best to try the second fix... Good luck!

BTW, there were six subfolders, but only one said it was the Primary IDE Channel AND had a MasterIdDataCheckSum key. The others had various things mentioning Master and Slave (kinky) but not in that format.

Do you have any software running to get around region encoding? DVD43 or similar?
Unplug and replug the cable from motherboard to DVD drive.
Try running some tests with DCSpeed2000: http://www.cdspeed2000.com/index.html
That should give you an idea if it's reading data from the disc OK. Try it with a few discs.
Clean the DVD lens - TBH, if you don't already have a lens cleaner, I'd just buy another drive. A lens cleaner will be £5-10. You should be able to pick up a new drive for £10-15 assuming you can use a SATA drive. If you only have IDE/PATA you'll have to pay around double that for a PATA drive, or buy a converter, or install a SATA card.

Y'know, Tex, I think you're on to something about the regions. My PC is set to Region 2, all the discs I'm trying are Region 2, but DVD43 checks them anyway. I'm going to try a few discs with DVD43 turned off before I attempt to play them, see if that's causing the interference.
I'll let you know, thank you!
