I have been chasing a problem with my latest myth installation. I
recently installed Mythbuntu 9.10 and MythTV .22 over my previously
working 8.10 / .21 version.
I have a Hauppauge HVR-1600 Tuner/Mpeg encoder card installed which
worked great in my previous install. It is connected to an outside
antenna and to the S-video out of my Dish Satellite Receiver. The ATSC
tuner/DVB half functions OK but the s-video mpeg encoder output
(/dev/video0) shows a black screen in myth frontend "watch tv" and a
red screen in VLC. When I request that a program be recorded from the
Dish receiver, I get 30 minutes of red screen along with the Dish
receiver audio when I "play it" back in Myth.
1. I though perhaps I had a broken/bad s-video cable. So I unplugged
the s-video cable from the HVR-1600 s-video jack and plugged it into the
Sony LCD TV. Picture fine. Normal picture on all Dish channels.
2. I though I must have mis-configured something in Myth. So I fired up
VLC and chose Media, Capture Device, PVR and entered /dev/video0.
Red picture in VLC with audio from the Dish Receiver, same as my
recordings. Certainly not
the picture I was expecting from the Satellite Receiver but at least the
Satellite audio was there. In VLC, Media Information, Codec Details
shows Stream 0, type: Video, Codec: mpgv, Resolution: 720x480, Display
Resolution: 720x480, and Frame rate 29.970029.
3. At this point, I think that the HVR-1600 analog section didn't
initialize correctly. But the DVB half did and plays OK in VLC.
Plus it appears that the cx18 chip was initialized as shown below in
the following:

5. In my old installtion of Myth .21 and Mythbuntu 8.10 I
had installed the gnome-desktop. As I said, that installation
worked perfectly with the HVR-1600. I can't see why this
would cause a problem.
6. In the synaptic repositories, I have checked
http://us.autobuilds.mythbuntu.org/mythbuntu/trunk-0.22/ubuntu
so I think I'm getting the latest updates.
A. Any suggestions on what to try next?
B. Does anyone out there have a HVR-1600 Myth.22/Mythbuntu 9.10
system working? (I'd like to compare notes.)
Thank you,
Larry
