DirecTV Serial Channel Changing...

[Bikeman]

What happens if you use the DTV remote to change the channel? You should see the channel change. If not, you have other issues. Remember that the HD-PVR only displays what comes out of the DTV box, it doesn't control or change anything.

You mentioned that you have only COM2 & 3. You also say that they're at non standard addresses and you are using some kind of channel changing program you wrote. I would change the COM ports to standard addresses and get rid of the channel change program before continuing.

I didn't have to do anything other than, update the firmware on the cable, plug it into the DTV box, push the red reset button and change the change mode to fast.

THANKS!!!!! This solved my problem!!!!!

I had to copy the .dll file to the common directory as well as enable "fast" mode in the advanced/customize configuration. Both fixes are mentioned in this thread.
