I suspect you can try if ffmpeg (the command line tool) 
and ffplay can read your file to answer this question.
(I don't think anybody else can answer the question 
unless you upload a sample which likely takes longer 
than testing.)

Isn't this a question for a PyQT-related mailing list?
FFmpeg (actually libavcodec, libavformat and libavutil) 
are C libraries, what you want is probably possible if 
C libraries are supported at all.
As an alternative, you can probably call ffmpeg (the 
command line application) from your PyQT project.

That depends on what you mean with "record".
FFmpeg for example supports capturing the screen 
on X.
For recording DVB, I would suggest cat (or 
mplayer -dumpstream).
