I just upgraded from an old 1998 WinTV card (on which I had a fully functional MythTV setup - via the bttv driver) to a WinTV-PVR 150; I run Debian Sarge, and I followed the howto directions for a Debian system from http://ivtvdriver.org/index.php/Howto:Debian. After modprobe ivtv, I do a cat /dev/video0 > test.mpg; when I play back the mpeg recording with xine, I just get static, visually and auditory. I've ensured that I am using us-cable (what worked before on my setup), and used ivtv-tune to change to a valid channel (I've tried several), NTSC. Can anyone give me any ideas where to look next? Thank you for your help! Please let me know if you need any more information. Also, I've tried using MythTV with the new card, and when I try to watch live tv, the tv goes black, and I can't get out without killing the x server.
I'll give it a shot, but things generally look normal in your syslog, except for one item :
ivtv 0.4.1 compiled and installed ok. I use kernel 2.4.27. Here is the relevent output:
modprobe ivtv; syslog output:

I'd say try 0.4.0 once and see what happens. 0.4.0 does not use hotplug (so the firmware files will need the old names and locations), while 0.4.1 does.
