[mythtv-users] unable to recognize channel

[Ricardo Kleemann]

Hi all,

I have mythtv 0.18.1 installed and working fine on a Fedora 4 system, with 
PVR-150MCE and a GeForce4 MX440 setup.

I don't really need to change channels in the sense that I expect the tuner 
to tune away, because I simply have a S-Video input into the PVR-150, so the 
video will always correspond to the input video source.

However, I do need to "tune" in the sense that I want the program 
information to match what I'm watching, so that when I record, it'll have 
the appropriate program info.

So what I have is a video source hooked up to Data Direct, and it grabs DISH 
network info. My S-Video input is the S-Video output from a DISH receiver.

The problem I'm having is that if I bring up the guide (say by pressing 
"S"), I can go to whatever channel I want, say channel 596 on DISH, and the 
guide properly shows the programs and info for that channel. However, if I 
select that channel, the "tune" doesn't happen. It's as if channel 596 were 
invalid, so it simply stays on the current channel. Let's say that mythtv 
starts up at channel 100, if I simulate going to 596 (either by typing in 
596, or by going into the guide and selecting 596), mythtv pretty much 
rejects it, and goes back to channel 100.

I tried altering my config so that the default channel is 596 (or some other 
channel), but "watch tv" always defaults to 100 and I guess rejects the 
other channel.

So I can never have the program info in synch with what is actually playing.

How can I fix this? I know that the Data Direct info is being picked up 
because the tv guide has the whole lineup and shows the various channels... 
but if I try to "tune" to that channel, it fails.

Again, I'm not really trying to tune, but I just want to be able to ensure 
that whatever I'm watching is reflected on the current program information.

What am I missing?

thanks
Ricardo
