1080i mkv movie, choppy on all players, CPU/Harddisk not to blame.

Hi,

I wanted to play back a 1920x800 movie on my Intel Dual Core2 computer under Vista with VLC, Zoom Player, MPlayer, etc.

I tried the tips from all similar posts. No success.

MPlayer is doing best but still not watchable. I have to say, even in action scenes the CPU never goes over 50%. Also Harddisk shouldn't be the problem.

Most annoying is that the audio gets out of sync more and more while watching. MPlayer hints how to fix it (problem with audio driver, use flag -audiosync 30). However this all does not work. Also -dropframes, etc.

I played around for many many hours and all players I know. No success so far. Zero.

Thanks,
sb

Please describe exactly how you encoded the MKV movie.

That because only 1 core is used. Mplayer, VLC has limited support for dulacore cpu's...

I did not encode the mkv myself. It has rather to do with the high resolution. Mkvs in general run pretty well.

Mplayer maybe, but VLC uses both my cores. Also they never use more then 50% of each core.

Yesterday night after posting I booted into Ubunutu Linux and installed VLC. There it runs without glitches, audio delay, etc. And I booted that Linux from USB!

Since the hardware is the same, even VLC is similar, I wonder why I get such a bad experience when using Vista/VLC?

Cheers,
