Hi all

I've been having problems playing back 720p MKV files on Windows 7.
I have a Q6600, 8Gb RAM, NV8800GT w/ WDM1.1 drivers, Creative X-Fire etc etc and all of this works perfectly using Vista SP1/SP2.

When I run video's on Windows 7 it chops a lot, like it's dropping 3-4 frames each second. This happens in Windows Media Player, Media Center and Media player classic. I'm using the Shark 007 x86 & x64 codec packs

The only player that runs everything I throw at it smoothly is VLC :confused:
...and I dislike VLC as it's a CPU hog and doesn't work with my media center remote control.

Any ideas people? I understand W7 is a RC so if theres nothing to be done at this point then so be it, but I'm just a little surprised considering the positive feedback I've seen so far. Other than this little issue W7 works beautifully.
 
Reprogram the hotkeys for VLC so it works with your remote.. that's my suggestion, I don't have any help for the other things!
 
last time I checked windows 7 had h264 codecs already (assuming that the film is in that). All you really need is a mkv splitter such as haali one and a sub reader if needed :).

Now I don't use windows 7 (yet) but I did notice in vista that if you installed an alternative dvd mpeg2 codec it would judder and I suspect this is a similar issue.
 
All i did was install Haali splitter and ffdshow separately and all mkvs work flawlessly in bsplayer. I have issues with codec packs for some reason :p
 
The latest Shark007 codec pack is working fine on Win7 x64 RC here. Are you still using a beta build of Win7 by any chance? I had this issue earlier on - around build 4700 or 5700 onwards iirc? At any rate, upgrading to the RC with a clean install and then adding Shark007's codecs fixed it all. MKVs and everything else play flawlessly for me using DXVA, in any player I choose. I hope this is of some help.
 
I've not used codec packs for years because of issues like this. On a windows install I install only a handful of things:

FFDShow Tryouts - general mpeg / xvid / divx / various audio formats decoding
AC3Filter - AC3 / Dolby / DTS decoding
CoreAVC - Fastest H.264 Decoder available
Haali Media Splitter - Allows you to play .mkv files.

That combination can play anything, and 1080p video barely tickles the CPU.

For playback I recommend Media Player Classic Homecinema, as Media Player Classic itself hasn't been updated in years.

Don't use 64bit players yet as the 64bit codecs suck, and you shouldn't need the memory handling of 64bit for simple movie playback anyway, even if you're playing a 40gb blu-ray rip!

Just installed the above but a 1080p video I tried was out of synch (sound didnt match and video was choppy). Also can't play .ram files.
 
Do you need a 64 bit OS? I'll get slated for this, but it might be of interest.
32 bit win7 + divx tech preview + haali splitter (if you want passthrough audio and proper thumbnails) = mkv playing fine in media center so no need for other players (also uses hardware acceleration if you have an ATI HDxxx card)
