[linux-dvb] Re: korrupt MPEG2 Stream

[MK <amk@befree.ch>]

You guys have been doing a really great work and I whish to congratulate you 
all.
Axel Gruber has some points however. 

I have also been having a lot of trouble doing anything useful with recorded 
streams (with pre-0.8 driver). Usually I record Arte and Tv5, and aim to put 
them in some format I can read store indifferently with other players: 
"SVCD", "SVCD-like" the so-called "mini-dvd" etc.
The most frequent problem appears as audio dropouts. The originally recorded 
stream plays OK and in sync, but things go lousy after demuxing and remuxing.
Most tools signal some error about the audio stream.
BTW there's a version of Flaskmpeg specifically modified to deal with pva 
streams. Couldn't even open _some_ of the recorded streams.

So it's not about any special "propietary" windoze software. The point is 
that ALL the tools I've tried, under windoze or linux, do have some problems 
with certain recordings, to the point of seriously interfering with further 
manipulations. 

My question is: has someone here run the recorded streams (from several 
different transmitters) through some analysis or "lint" tool? this could 
maybe help to troubleshoot what's been going on.
