I used to have a similar problem when using my "dvbstream" application which 
RTP-streams the TS from /dev/ost/dvr over the network. I too used to dump the 
stream to files in the same way you did.  However, I found that only the 
following two commands were needed:

cat /dev/ost/dvr | ts2ps vpid apid > file.ps
mplayer file.ps

The command-line I now use to view the stream is as follows:

./dumprtp | ts2ps vpid apid | mplayer -cache 4096 -

However, this is still not 100% perfect - I still get the occasional "jumps" 
in the playback, or occasionally, the video and audio lose sync badly (very 
slow video playback, audio playback fine).  Restarting mplayer then fixes it.

NOTE: "dumprtp" is equivalent to "cat /dev/ost/vdr" - it just dumps the TS 
from the network.

It's also work keeping up-to date with the latest Mplayer CVS versions.  I've 
found that it's ability to play files from stdin has improved a lot over the 
last few months.

Dave.
