I'm having a problem with some videos played on the HTPC. It's fast enough

Windows 7 64bit
AMD 245e CPU
4GB RAM
ATI 5450 PCI-E videocard
Onboard sound, coaxial/optical out
Pioneer LX-5090 plasma
DVI-HDMI to Yamaha AV amp, onto Samsung 24" monitor
HDMI-HDMI to Oppo switcher then onto Pioneer

Should I set the Pioneer to 24hz? If the movie is 24hz, should I do that or setting to 60hz ok for all videos?

For movies the Pioneer is set to primary and I just load up MPC and start the video. Dual display is set to single screen, as when I switch off the Samsung it seems to mess around with dual display then sets single display mode. So I just have the Pioneer to primary.

Media Player Home Cinema edition 64 bit.

There are a few options in ATI, I've disabled all the post processing except for de-interlace and enforce smooth video playback. I've noticed a few things like real time correction, vsync, etc. MPC HC is using the ATI hardware acceleration.

MPC HC has a ton of options, all I've done is set DTS/DD SPDIF output

I tried the movie in VLC and it seems to keep the audio in sync. But I prefer MPC HC.

I have tried other videos and some do go out of sync the longer I leave it. The tearing test looks fine.

Your question might be better asked in the Home Theater Computers sub-forum:

ok. can a mod move it?

I notice MPC HC has audio sync however it's not like it's out straight away. Sometimes it takes a while for it to drift.

This is doing my head in.

I think it's only out in Dolby Digital. In DTS it seems ok

So I don't want to apply delay in the HTPC or on the processor because then DTS will be out.

Right I put a 250ms delay and that seems to fix it, when viewing on the plasma, but on the monitor it's out of sync. Corrected Dolby Digital, I haven't tried DTS.
