Okay, I was able to get the FusionHDTV stuff working with QAM256, and with MythTV. For QAM, I just switched my cable to the other RF input. Apparently the OTA/Cable association with the inputs is just a function of the Fusion Windows software. After doing a full ATSC scan, I did a QAM256 scan, and it recognized most of my channels. After tweaking around with the MythTV channel configuration a bit, I still don't understand it.. but it's working. I just manually entered the frequencies associated with the various QAM channels (I used the Mythweb UI, but it could probably be done in other ways). Also, make sure the "Starting Channel" is defined as a valid channel number when setting up the input connection. If it's not a valid channel, MythTV doesn't give any decent feedback, it just shows black screen. The QAM channel scan in MythTV picked up most of my available HD channels, which are just retransmissions of the OTA ATSC channels (PSIP data and all). So, MythTV sees the channel, including the call letters and subchannels. There are also a couple non-ATSC, but unencrypted, channels on my local cable system, such as ESPN-HD. The channel scan did not pick these up, so I need to figure out how to manually add them. -Todd BTW -- The MythTV channel configuration is _terrible_. I hope it's not so bad when dealing with standard NTSC or PAL broadcasts. I wish they would use an easier config format for the basic system config stuff, like a simple text file. I'm sure the MySQL stuff is great for guide data, but for application config it just makes everything overly complex. (sorry, just had to rant a bit after struggling with this stuff.. I know this is not a MythTV list..)
