I bet sound is burning you. Audio not set up right and it will hang.
Think about installing the Alsa drivers. Also do a 'ps -eadf|grep
aplay' If you see aplay running, kill it. Not sure myself what it
is(havn't taken two seconds to look either ;-))
but I have a problem some times with it on my Mandrake 9.0 box. Make
sure that it is not running and then try to start tv again. Might have
to restart the frontend also.
