The VideoLAN Forums

I have a WMV9 1080p avi film (Tombstone) that I tried playing on my system:

P4 3.2GHZ 1GB RAM GeForce 6600GT WIn XP

With WMP11 playback is incredibly jerky and sound drops out of sync by many seconds.

I tried the latest VLC and is much better, with sound in perfect sync. But the video isn't fluid and looks a bit like an old stop-go animation, as if lots of video frames are being dropped.

My 720p and 1080i demos from the MS website playback great, I never tried 1080p until now. Any ideas to help, or is my aging system just not up to 1080p?

Try Media Player Classic (Gabest) and Purevideo decoder from NVIDIA http://www.nvidia.com/page/purevideo.html
try Overlay and VMR-9 modes on Media Player Classic

Because your PC is too slow ...

While both VLC_help and j-b are probably correct I have yet to appreciate why people are trying to do this??? I mean it takes a very large monitor (52" to 65") to begin to appreciate the difference between 720p and 1080p and the 2.4 to 3.5k to drop for what, problems and unresolved standards??? Other than this is the time and space to deal with the file. So is this an exercise in trying to see the limits of your machine?

Trying being happy with what you have rather than spend lots of time and frustration worrying about or trying to resolve what you have not. Next year there will be a new model for half the price that will do everything you want.

The first of the new players/recorders are out for both the blueray and HD mpeg formats. Do they actually work as claimed? Or do they have problems. The TVs and or projectors that will do 720p or 1080p have been out for some time now, do they work or are there restrictions for there use? Or perhaps you still think it's a matter of doing the research then finding and buying the right one, then think again! While there are some reasonable solutions for 720p, I'm not sure there is for 1080p or will be any time soon. I guess only time will tell.

If you really want to do something worth while in this area start making comparisons of the interlaced standards versus the progressive standards and look at the differences between say 480p and the DVD. Then know that the HDTV standards and restrictions are not worth the buy in at this juncture. Try complaining to the powers that be with regard to these standards and restrictions and YOU may make a deference with regard to the future of 720p and 1080p. Somewhere over the rainbow I'm sure there is an answer just for you!

It took me a long time and money to come to these conclusions and at this juncture I can make some eye popping 480p files and am still experimenting with 720p. So what I'm saying here is not without some experience.

No. My pc is rather aging but my 1920x1200 Dell 2407WFP isn't. When I got the 1080p running properly it looks astounding on that screen, 720p was excellent but 1080p is awesome. I don't yet have a fancy dual-core system or the like, but then again I feel sorry for you guys with titchy monitors missing out (only jokin)

I installed CoreAVC and was promptly rewarded with a hive corruption that even took-out System Restore, never had such a bad crash. I re-installed WinXP fresh and was surprised to see the 1080p play smoothly with WMP10 with no extra codecs or other software installed.

So thanks for the help. FWIW I accept 1080p will probably remain a 'now and again' treat for the time being as the files are way too big.

I will stand by my statements! Awesome is hardly what I would call it.

Perhaps "very nice" when viewed on a PROPER display. Which is noted and agreed upon by most professionals to be 52" to 65" and in addition it should state in the specifications that it's 1080p compatible. Many are not.

So I don't know what your looking at but I've been through this and do allot of editing in 480p and some 720p. The other possibility is I have become accustomed to the newer resolutions and the anticipation of moving to 1080p for me is just "real nice" and for you just beginning to experience, it is "awesome".

Ya! The CoreAVC codec is probably the best one out there. But it doesn't crash my machine.

my screen is a 24-inch 1920 by 1200 native. what on earth are you rabbiting on about 'size' for when it is resolution that matters. do you have a screen that shows full 1900 x 1080p and not some horizontal scaled poor-relation? if not how can you comment on what it looks like?

the core package trashed my os. it did not trash yours. your point?

I too doubt that CoreAVC messed up your computer, and CoreAVC is H.264 decoder, so it won't help on WMV.

And about those resolutions. If you have 24 inch monitor you have to be watching movies at least 2 meters away from display. Seeing diffenrence between 1080p and 720p from that distance gets harder (assuming media player scales 720p correctly).
