Hi, had same problem, solution is:

in mythtv-setup, when defining a channel, on the second page at the top there is a box called "Freq ID" or similar.

Into it type a uniqe number (I use 1,2,3,4 etc sequentially, not sure what works or not)

DOing that for each channel seemed to solve the problem

(I had exactly the same problem as you, channels not changing, lots of CheckChannels failed etc...)

BTW: The admins should allow guest to post replies - I took me a good 4 minutes just to register to post this short message!!!)

[ Summary: cannot change between channels with composite or s-video input ]

I believe I have the same problem:
I have 2 video sources defined --1 for over-the-air broadcast and 1 for input from my satellite receiver (using composite input). I am able to change channels from one broadcast station to the other with no problems. However, when I attempt to change from one satellite station to another satellite station I am not able. There is a pause and the buffer is cleared but the channel # does not change (on my mythbox). If I alternate between satellite then to over-the-air then back to satellite the channel does change, displaying the proper information.

I feel I need to reemphasize what I believe the original poster was trying to state: I am not concerned with my mythbox being able to change the channel on my satellite receiver with an IR blaster. I will do that with its supplied remote for now. What I wish is for my mythbox to display the proper program data so that I may view the program data and have the one-button-record record for the proper duration.

“BK” said to define the Frequency ID number but these have always been defined and the problem remains. I even did a simplified test with only 1 video source and only 3 channels each with unique Frequency ID numbers. Still no success.

After days of searching, this post seems to be the only one that describes this particular problem. Any suggestions are appreciated.

Do you have a dummy channel changer script that reports success?

I'm not sure how this stuff is handled, but I'm guessing that if it is expecting to change the channel by external means it is also expecting a success/failure indication.

Try this... Run mythtv-setup, and edit the entry for the card which is connected to the satellite box. Set the external channel change command to be "/bin/true".

TJC,
Thank you very much. That was it exactly. I ran mythtv-setup and under input selections I entered “/bin/true” in the external change channel command. I hope I didn’t miss that somewhere in the documentation. It makes perfect sense... nothing was telling mythtv whether the channel changed or not. Now it works perfectly.

OK here we go again!!! :)

I'm still having the issue where the channels will not change.

i have however found out something new.

I incorrectly set my capture card (menu 2 in mythtv-setup) to use composite 0 and set the input connection (menu 4) also to use composite 0.

The channel data then changed and my IR sender changes the STB but I had a black screen, as the input was incorreclty set.

However if i correctly set menu 2 and 4 to use composite 4 the problem comes back and the video is now displayed.
I have also tried to use svideo0 but the same issue occures.

can you create a symbolic link to make it use composite0??
does any of this make sence to anybody??

Does anybody have a clue how to resolve??

Answers on a postcard...... :lol:

(I'm going mad over this issue... please help!)

## edit
P.S.

I have just noticed that the starting channel in menu 4 is being removed
only when I initiate the "Watch TV" option. if i run myth and then close it's still there
## end edit

I can't get my "up channel" and "down channel" commands to work consistantly. I am in Los Angeles, California. I have the following channels in my area (partial list):

2_1 (or 21)
4_1 (or 41)
4_2 (or 42)
5_1 (or 51)
5_2 (or 52)
7_1 (or 71)
7_2 (or 72)
7_3 (or 73)
9_1 (or 91)
11_1 (or 111)
13_1 (or 131)
18_1 (or 181)
...
62_1 (or 621)
62_2 (or 622)
...

I can change up or down between 7_1 through 62_2 (71 through 622). However, I cannot change from 7_1 down to 5_2, 5_1 down to 4_2, or 4_1 down to 2_1. Attempt to change up fails too.

How do I configure my channel list to fix this problem?

The excerpt from my back end log file shows the error encountered when my MythTV fails to switch between certain channels.
