I've been struggling with this problem a lot, and I think I've tried almost everything. I usually get frustrated, reformat and start over, but I still can't get it to work.

First, if I understand correctly, these are the steps I think I should be doing to get knoppmyth working with my pvr-350 and tv-out via s-video.

1. Install Knoppmyth (everything seems to be fine here)
2. Run myth-setup and mythfilldatabase (everything seems to be fine)
3. Reboot my machine - remote and tv-out don't worl (typical)
4. Follow directions from here: http://www.knoppmythwiki.org/index.php? ... stallation
5. Reboot -however, my computer hangs on boot after it initializes ivtv

I'm using /dev/fb0 & and I think my 350's busid is 05:04:0(not totally sure if I wrote it in right in the XFree86-4)

Please help me - I'm going crazy!

Here are the outputs of some useful things:
lspci:
0000:05:04.0 Multimedia video controller: Internext Compression Inc iTVC15 MPEG-2 Encoder (rev 01)

/etc/mythtv/modules/ivtv:

(line breaks got messed up on that one - its the same as the link I posted above, plus the 'options saa7127 enable_output=1'...line.
