Purevideo enabled = jerky HD-DVD playback. What's the deal? :(

I keep getting stuttery playback on my 7900GS when I enable Purevideo in PowerDVD 7.2 (HD-DVD version). Turning off Purevideo gives me smooth playback.

I feel like, though, that if I have a card that supports Purevideo, it would make sense to be using it? This is a fresh install of XP Pro, and it stuttered with Purevideo on with my previous installation too.

Drivers: 93.71.

I didn't download any Purevideo separate installation, as it appears that Purevideo is just built into the drivers? Or am I missing something?

Thanks all.

Specs:
Shuttle SN27P2
Athlon 64 x2 4200+
2GB DDR-2 800
Geforce 7900GS HDCP 256MB
3x 500GB Western Digital RAID 5

Hardware acceleration w/ PowerDVD Ultra is screwed up right now. Everyone is getting bad results with hardware acceleration enabled.
Not sure if it's PowerDVD or the Nvidia drivers, but since I'm pretty sure that ATI users are having the same issues, I suspect the fault is with PowerDVD.
Hopefully it'll get fixed soon...

I also have a 7900GS, using the same driver, but I don't have stutters. Some stuff even played alright even on a single core A64 at 2.25 GHz before I upgraded to Core 2. The picture was smooth, just the colors were horribly messed up, and trying to fix them messes up DVD playback in MCE. So I switch hardware accelleration off.

Hardware acceleration in nvidia's Purevideo plugin for WMP10 seems to be broke for Geforce 8800 series too (playing a .TS file will freeze the system with hardware acceleration on). Lame.

Well, I am not with my cheap evga 7600GT. Playback is excellent and CPU utilization is under 55%. I am using 9792 from the http://laptopvideo2go.com.

Interesting. Downloaded the 97.92s and I loaded up Mission Impossible 3 HD-DVD, and I got the title screen and menus, and as soon as I pick a scene, I get a black screen and no picture. Went back to the 93.71s.

Arrgghh. According to nVidia's latest 97.92 release PDF, overlay was broken in the new Purevideo release, but not VMR. If anyone else is having trouble with 1080i .TS playback in WMP, switch your "Enchanced Nvidia Support" options in Purevideo to VMR9.

I replaced evga 7600GT with XFX 7600GT and I am using the same 97.92 drivers and playback is perfect and CPU utilization is around 20%. I am using PDVD 6.5 though, not 7.1 ultra.

Yep, 6.5 works fine with h/w accel. 7.1 does not.

7600 and a 7900 = no luck with 7.1 - no probs with 6.5.

So the consensus is 7.1 sucks big way.

Doom9, the owner of http://www.doom9.org, is implying that 7.1 actually downreses the picture.

Adding insult to injury.

Doom9 has a lot of experience, lot of users on his forums and huge display.

Cyberlink, we hope you are listening.

7.3 under vista using the 100.65 Nvidia drivers and a Geforce 8800 GTS works great with PureVideo acceleration enabled. Submit a support ticket to Cyberlink via the members section of their web site and request an upgrade to 7.3 and see if it fixes your problem.

Submit a support ticket in the member section of Cyberlink's web site and tell them that you have both an HD-DVD drive and a Blu-Ray drive and they'll send you the download information and key. Did so when I picked up my Blu-Ray drive today and I got a response from them without four hours or so with the info.

Rumour has it 7.3 is a week away. No idea how accurate that is though.

i get 7.1 to work (under xp only) using 8800 GTS with hardware accel enabled (and got it to work using VGA with 7800GT). 100% smooth, no banding, no downrez. i do run it to an HDCP LCD though. it is true that they seem to flag stuff even though the HDCP should not be set for on any discs for at least two years.
under vista i get instant crashes when trying any hi-def discs.

And how do you know there is no downres?

Check Doom9's posts in this thread:

I have no reason to believe he is is biased against 7.1.
