Audio sync setting in Windows Media Player 11

[atreides93]

I noticed last night that if I was watching mp4's in Windows Media Player 11, the audio would often get out of sync if I seeked around in the video. It was incredibly annoying, especially since it didn't seem to do it on all my encodes.
Then I saw a setting in the performance tab that says: Drop frames to keep audio and video synchronized. It was unchecked...so I checked it, and now it seems like I can seek without losing audio sync !!

The other alternative was to just use windows media classic.. which seems to start up faster and seeks faster anyway...but I thought I'd share that since I think most people don't even bother with WM 11 ?

Which MP4 decoders were you using to play the video?

Sorry yes I meant Media Player Classic.
I thought I was using the codec that came with the klite codec pack to play back h.264 but looking at the ffdshow video decoder settings I see that h.264 is disabled. When playing back in windows media player 11, the properties list :CyberLink H.264/AVC Decoder (PDVD8): so I see its using the decoder that came with powerdvd 8...and the nice thing about it, is in windows media player 11 it seems to use the hardware accleration of my Geforce 8800gt.

If I play back the same video in media player classic it uses 40% cpu...but in windows media player 11 it uses only 5%...sometimes 2% :) crazy!

so ironic it was loses audio sync..now that that's stopped...i'm definitely using media player 11 because of the hardware acceleration support...
which means using something like coreAvc for a decoder wouldn't be very useful for others who have this common video card and power dvd 8?

I had to actually disable the ffdshow video decoder in wmp 11, I had the h264 disabled in ffdshow like you, and it definitely played high bitrate h264 streams better, but it wasn't until I went into the settings and told ffdshow video to not run in wmplayer that I really got the hardware acceleration.
