	Hello Eric, 

I re-encoded the ogg video to -p preview and the sync problem is no loger.

I have had the same problem encoding a vob with -p pro, the video sync was out  
but if I encoded the vob with -p preview. The encoded video was OK.

Conrad Parker:

On this mailing list ask me for a sample of the video that was encoded with -p 
pro to check it out. Conrad could play the sample video on his machine with 
no problems. Conrad all so check the video file to see if any thing was 
wrong. The sample file was perfect. 

If  I encode a vod with -p pro on my machine that as 250 meg memory.
I can not veiw the video because of the sync is go out. 
But Conrad can veiw the same video without any problems.
The memory size on Conrad machine was 2 gig.

I can play the ogg video "Elephants Dream" thats encoded with -p pro with out 
any problems and the all the test video files for theora play OK.

The video :	076_Knowledge_Power_and_Free_Beer

Which is encoded with -p pro

As the same problem that the sound and video sync is out and the video stops.
I bet if the machine that I play it on had more memory than 250 meg the video 
would be OK ?

If you have time check out if you can play one of the videos that I am having 
a problem with on a machine with 250 meg of memory. To see if its just me or 
its a genral problem.

The idear I have why I can play some files that have been encoded with -p pro 
is that these files have been encoded on a machines with a lot of memory ?

	Thanks for your time and your reply :	Eric
