Re: [gentoo-user] video capture

You have a pvr-150 which has onboard mpeg2 encoding. Most standard v4l
software will not play tv from such a card, because it expects a different format from the card. For example the tvtime supported cards
list says:

"The ivtv driver supports cards that provide high quality MPEG2 encoded
video. This cards are ideal for PVR systems. However, tvtime has no
MPEG2 decoding capabilities or audio playback code, and therefore cannot
be used to watch live TV from these cards."

Try 

cat /dev/video0 > test.mpeg
ctrl-c to stop
mplayer test.mpeg

or just:

mplayer /dev/video

you can tune the card and adjust the inputs etc with the tools provided
by ivtv. Mine is permanently set to the composite inputs as it used for
the output from a set top box. I have never used the tuner. getting an
external composite video signal like a set top box output a VHS player
is a good way to test. Move onto the tuner once you are sure you can get composite to work.
