I'm trying to set up my 5500 for analog cable only and have hit a similar
I can get V4L working perfectly on my box--I can watch live tv and schedule
recordings--but if I switch in and out of "Watch TV" mode, the backend will
crash, sometimes taking the frontend down with it. This isn't really
acceptable for media center use when someone might accidentally go to the
MythTV menu and want to jump right back live TV.
Using DVB, when I set up just the "Television" input source, it doesn't
work. When I go to Watch TV, I can change channels but all I get is a black
screen on all of them. On the bottom of the screen is a message about
signal strength, which might mean that it's trying to use the DVB input
device to get Television channels, which of course won't work. This is
despite the fact that MythTV has the DVB device set to "(None)".
I've gotten DVB drivers to work by setting up two input sources for the
card. I set up the "Television" input source as normal, and set up the
"DVB" input source with some dummy data--in this case, the same analog cable
data as the "Television" source. When I start live tv, it starts on the
blank DVB input source, but then I hit "C" and it switches to the Television
source and all is well--until I try to schedule a recording. Every
recording I schedule has a "Recorder Failed" error that looks like this in

Note the "dvb tuning parameters" line. I'm trying to record analog cable
with my Television device, not DVB.
Back to your message, are you saying you got V4L to work without any hitches
on your 5500? If that's the case I can look to updating drivers or a
reinstall to remedy my problems, and just use V4L since analog cable is all
I have. On my box, it seems that V4L is just much less stable than DVB, and
I also get 3-second long pauses intermittently, when my box should have more
than enough power to do regular live TV recordings (AMD 4400+, 1 gig of
