Thank you for your answer! But that is definitely not what I was
directly heading for ;-)

I know what MythTV is (actually I am using it for over 5 years now) and
I have reasons why I want to use it in that way.
I am interested in a deeper configuration and would like to know if it
is possible to reduce the size of the files.

I would be very glad if you (or anyone else) could give me a more
technical answer to my question.

Thank you a lot,

If that's your goal, you may be better off with a different TV
application designed for LiveTV--like xawtv or tvtime or whatever.

Myth is really a DVR, where the "R" means "Recorder."
