Has anyone tried the infamous "Bird Scene" with a PCH?

Mine was about the same as -stattik-'s. I think I had three brief stutters during playback.

Interesting. Mine stuttered significantly more but I was reading the file off the network. Did you by chance play it off a connected hard drive or flash drive?

I played it through GB-PVR, which means it used HTTP stream, which is supposed to be much more efficient than playing a video file off a network share. Maybe you played off a share?

Even if GBPVR streams by http to the PCH, if GBPVR has to read the source file from a Windows or NFS share I'd expect poor performance unless you have an amazing file share and 100 Gig ethernet.

Not a problem for me. My GB-PVR machine has its storage locally connected.

I had an interestig issue playing that file on my GBPVR machine. Using Cyberlink and Arcsoft decoders, I could only get it to play if I used the VMR 7 or 9 renderers. If I tried to use EVR, I got no video. The only way I got it to play with EVR was to use FFDShow.

There was not much CPU difference. CPU usage was 80-100% on a 5600+ AMD X2 processor with a 9600GT. Out of 10+ plays, I got stuttering only once (even though CPU peaked at 100) and it was only in the last 2 seconds of the clip.

File was stored on an eSATA drive locally connected.

It was most likely trying to use hardware acceleration, but I'm fairly sure these video cards only support L4.1 encoded material. If this is L5.1, then its probably using features the hardware acceleration doesnt support. ffdshow doesnt support hardware acceleration, which is probably why it worked.

Ah, didn't think of that. Turning off DXVA made it work.

It was played off the network via GBPVR. I noticed that after playing certain large MKV's that I experienced more stuttering with the Bird Scene. Perhaps memory isn't being released at times.
