On advice I switched from DivX player to VLC and until now had been great.
Usually new video files come in at AVCHD format and play OK
However just recorded a bundle of these at 1080p .... and VLC seems unable to play them properly.
Audio is OK .,.. but video is very choppy.
Read that it could be incorrect use of cores ....
My PC is Intel Twin processor 6600 2.4GHz (4GB RAM) running VISTA 32 bit, when playing a file on VLC (ver 1.1.11) the PC shows core 1 running at 70% core 2 at 45%
The Media info file shows it's :
BluRay Video
28Mbps bit rate
Format High@L4.2
Video bit rate 25.7 Mbps
50 fps
If I drop files into Sony Vegas they play OK ... I found some advice to change these settings:
Select “All” under "skip the loop filter for H.264 decoding"
Made change however it made no difference.
Should I be getting the Graphics card to do more - I have an Nvideo Geforce 7900 GS .... anything I can tweak ?
1080p plyback very choppy

Re: 1080p plyback very choppy
What about activating GPU decoding in preferences?

Re: 1080p plyback very choppy
Went to link for GPU decoding ... and it states that for the Graphics cardWhat about activating GPU decoding in preferences?
"you are required to use a GPU supporting PureVideo in its 2nd generation (VP2 or newer)"
As mentioned my Graphics card is 7900 ... and if I read the compatability matrix correctly it is only VP1
Re: 1080p plyback very choppy
also just tried for comparsion MPCH ... this plays video perfectly but sound is now choppy ...
and it's different result.
Video now plays fine, but audio is choppy .... i.e. keeps dropping out to no audio ... clear when it does play it. (not distorted)
Processor working at about same level.

Re: 1080p plyback very choppy
Tried nightly build ... strange performance .. no video at all for first half of files ... only audio, then video would come in and it did play cleanly no choppiness at all.
I tried it on several files ... it only plays audio and gives blck screeen for first half of clip.
Processor is running at about 65-75% on each core.
