DVD Playback Slooooow...

[deajshin]

I have Windows XP Media Centre Ed with all recommended updates. Recently I
have noticed an issue when playing DVDs, the video and audio plays really
slowly. This happens in Media Centre, Windows Media Player and WinDVD. I have
tried different DVDs and have the same problem with all, however playing
video or music files from the hard drive is not a problem... just the DVDs!

Any help would really be appreciated... I have tried the following:

Changed video settings from 32 bit to 16 bit
Made sure hardware acceleration is on
Made sure write combining is on
Reinstalled dvd drive
Can't think of anything else...

Thanks
Jane

Hi there,

I'm experiencing the exact same problem as this person above... anyone
know what's causing this problem and how to fix it? I know for a fact
that it's strictly a software/driver issue and not related in any way
to hardware. I happened to purchase 2 identical HP PCs and intially
both were fine and then after about a week one of them began to
exhibit this DVD playback problem. I swapped the hard drives and the
problem followed with the hard drive over to the "good" PC and the
problem was gone from the "bad" PC. My fear is that eventually this
same problem will surface on the "good" hard drive... BTW, neither PC
is connected to the Internet (by design, since I'm using them as stand
alone workstations).

Thanks in advance,
Dave

You might check that the DVD drive has not regressed to PIO
transfer (can be caused by sufficient errors encountered while
reading discs).


DMA Mode Enabling Instructions - for Windows XP:

Right-click My Computer, located on the Desktop or in the start
menu, and choose Properties

Select the Hardware tab

Click the Device Manager button

For each channel in your IDE/ATA controller:
Click the Advanced Settings tab
Under Transfer mode, select DMA Transfer mode, if available,
and click OK

Click OK to close the Device Manager dialog

Close the System Control Panel

Once you have rebooted review the steps above to make sure "DMA
if available" is in fact still set. If your computer is unable
to keep this setting you might need to contact your PC or DVD
drive manufacturer.
