I posted the stuff below on the mythtvtalk forum and it's been a few days and I've heard nothing. I've also searched for answers elsewhere, but no go. Since I'm running my setup under gentoo, I thought I try this list. I hope you don't mind.
I recently acquired a new Hauppauge WinTV 1600 and have successfully gotten the analog side working with the analog channels (1-99). That is, I can plug my (Comcast) cable from the wall to the tuner card's analog input and get the basic cable channels. However, the whole reason for getting tv tuner card and mythtv was to record japanTV, which is beyond channel 99 and requires a set top box to watch it on the TV. I've read the installation instructions for the ATSC input of the card but I'm having problems and am aware of the IR blaster option. I suppose the main problem . . . the one causing the other problems like not getting any channels is that mythtv is not "seeing" my card. When I go to configure the capture card there is not DVB DTV card type offered, which suggests to me that card is not being "seen." Suggestions? I have posted below some various info, but before that I want to ask one more thing, if all were fine, should it be the case that I plug the cable from the wall to the ATSC input (i.e., not through the set top box) and it just work (as if it were the set top box)?
