AFAIK dumping a PS requires one video and one audio PID - if you get TS 
from the card you can specify more PIDs (and the special 8192 PID to dump 
the entire transponder on the budget cards)....

Hang on, is this a software-only patch? I'm puzzled now, because I'm sure 
it looked like you had to use a soldering iron...

Anyway - it would be great if someone could tell the list the difference 
between "filtered" and "unfiltered" TS. If I understand correctly one can 
get a so called "filtered" TS (transport stream) from a full featured 
DVB-card. Furthermore if I undersand correctly vdr uses these TS streams 
(filtered if from a full card, unfiltered when from a budet card) when 
recording and pipes them through remux.c to save a PES to the disk.

When doing so it ignores the PTS used for A/V sync -- either because they 
are already correct in the "filtered" TS (but then what about unfiltered 
streams from budget cards) or because it's reckoned that PTS is not needed. 
Could someone please enlighten me on this issue?

If you feel it too OT for linux-dvb feel free to post this over to the vdr 
list. I just though the issue about TS came up here so I might as well ask.

Thx,
Gregor
