Everything seems fine in the dmesg output. When you run tvtime and get
"no signal", which input were you on? Was it "Television", "Composite"
or "S-Video"? If you are trying to tune to an analog channel, make
sure you are on "Television". You can change the input source by
pressing "i" on your keyboard when the tvtime window is active (the
on-screen display will show which input source it is on for a few
seconds). When you are in "Television", tune to a channel that you are
sure you have signal on by typing in the channel number and press

The sound would not work in tvtime unless you do "arecord -D hw:1,0 -f
dat | aplay" in another terminal (and keep it running there) before
running tvtime. This way you will get audio, but it will be out of
sync with the video, but it will at least tell you the card is
working. Then you can move onto other software that can handle the
audio better.

Ok, I did the arecord -D hw:1,0 -f dat | aplay in a fresh terminal, and then ran TVtime.  I could get sound out if I had the source on composite.  I still got no video on Television.  I know the card is working, now I just have to figure out how to get it working in something different than tvtime.
Thanks again.
