Not sure if this is the right ng for this, but hopefully someone here has
either cured something similar or can help out.

For several months I've been able to play DVDs on my computer, using
PowerDVD 5, with no problems. Since then, I've been doing some research on
backing up DVDs and I've downloaded some tools to help with that: DVD
Decrypter, DVDStripper, MenuEdit and IfoEdit. They seemed to work great but
I noticed the "Preview" feature in DVDStripper gave me very choppy play and
no audio. At first I figured that's how the preview worked (even though it
used PowerDVD) so I went ahead and had DVDStripper process the files. I then
tried to play the rocessed movie from the hard drive using PowerDVD and it
was choppy and audio free. So I figured the processed movie was hosed.
Eventually I tried to play the disk from the DVD-ROM drive with PowerDVD, as
I had several times before, and now it was choppy and audio-free. So,
obviously, something got whacked with the computer.

I have installed no other software in this timeframe. If it matters, I'm
running XP SP1 with 1GB RAM and a P4 2.4. I have a 16x MadDog DVD-ROM and a
TDK 440 dual format DVD burner (playback is the same using the burner) which
are alone on separate IDEs. As I said, playback was great up until recently,
so the machine can handle it.

I tried the XP troubleshooting wizard and Google, but was not able to find
anything useful. Both IDE controllers have "DMA if available" set and the
video (nVidea Ti 4200) drivers are up to date.

I also tried uninstalling and reinstalling PowerDVD.

I do not know much about codecs but that's obviously something that could be
the culprit. The utilities I've added do not seem to have their own codecs
but I am not sure. I found a utility called GSpot which looks for codecs on
the system. It reported something like 24 video codecs on my machine, which
seems high. I have yet been able to determine which codecs would actually
get used for playback. I also do not know which ones I would want to have
used and how to change it if necessary.

Anyone have any thoughts? Thanks in advance.

I was disappointed to see that you did not receive any responses to this
well-written post. I too am suddenly experiencing choppy MPEG-2 playback
(video/audio) in Windows Media Player and Cyberlink PowerProducer (when
previewing video in a DVD project). CPU usage fluctuates near 100%.

MPEG-2 video plays fine in Cyberlink PowerDVD. WMP and PowerProducer play
and preview MPEG-1 video without problems. I'm thinking it's a codec issue
too as I have reinstalled and updated my video and audio drivers multiple
times without change.
