pretty good card for what it was designed to do. originally got it for mythtv which it worked excellently for. uses the cx25840 kernel module along with the modules included with IVTV (with some firware...). Initial setup took about 30min and updating the modules after kernel recompile takes about 30 seconds or so. i run it using just mplayer with a couple filters and use ivtv-tune to change channels

to start it i use:
mplayer -vo xv -vf ivtc,hqdn3d /dev/video0

output is nice but moving it around is pretty ... interesting. the opengl video output, performace-wise, is better and looks almost exactly the same but will not work with the hqdn3d filter (at least for me).

This card is absolutely perfect for what I want to use it for. Requires the ivtv drivers with firmware put in /lib/firmware.

Viewing works perfectly with "cat /dev/video0 | xine -".

Changing channels is awesome, you can use "ivtv-tune -f FREQUENCY" to manually tune in to a channel, and (like I did,) use a perl script to scan for channels:

#tvscan.pl
foreach $channel (0..1000) {
system('ivtv-tune -f ' . $channel);
}

and start the script using "perl tvscan.pl > channels.txt"
It's not a very advanced script but I couldn't find a way to catch the output of system() to check for a "(Signal Detected)" message. Open the file and remove the lines without "(Signal Detected)" to get a list of ranges for your channels.

To stream, start a client with "nc -l -p 5000 | xine -" and the server using "cat /dev/video0 | nc CLIENT-IP 5000".

Worked great for my MythTV box. Used module-assistant to build the ivtv modules.

Sometimes I wish I had another input like on the PVR-350 for multiple show recording.

Excellent for what it is. Capture analog TV, S-Video or Composite and stereo sound and use its own hardware to convert the streams to MPEG 2. Therefore very low CPU usage. Use v4l2-ctl to change inputs. The video comes out at /dev/videoX (X will be a number 0 or higher). You can copy this output directly to the hard drive. (cat /dev/video0 > output.mpg) The output will be video and audio together in an MPEG 2 format. Capturing S-Video at 720x576 results in about 3GB per hour.
