My lspci and lsmod are identical to yours. I got tvtime working, too. It's 
just the kmplayer/kplayer/mplayer/xine/videolanclient problem with playing 
the tv feeds, as indicated in the documentation with tv://channelnumber.

The reason I want to do this is because I want to record what I am watching, 
like say... a videocassette sometimes. kmplayer has recording capabilities, 
using mplayer, I believe, but I have only ever gotten this to work with 
recording an mpg file (not very useful, since I already have the mpg file), 
and never TV. It worked with xawtv, but unfortunately, it created 2 files, 
one for video and one for audio, which was rather silly. How are you suposed 
to play that back? There is a program under windoze to reunite them 
(flaskmpg, bbpmpg and another one), but I don't wnat to resort to that. I 
want to use Linux tools.

I realize that there are some pvr applications, like mythtv, but they are 
overkill for what I want to do, I think. I rarely tape anything from tv, but 
just want to make clips from videos, cds, live streams from the web, etc 
mostly.

In fact, I did try to get mythtv recently, but ran up against the same 
problem with the repo timing out or no further repos to try. This problem 
has existed with dag and atrpms for a number of months now. I could just 
download the components manually, but mythtv's dependencies are a nightmare 
to manage by hand. Again, this seems overkill for what I need.
