[gentoo-user] Mythtv ATSC WinTV 1600

I hope you receive the stuff below with a grain of appreciation. I've
asked for help on the mythtv forum, but have yet to get it.


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 wan 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)?

Thanks for your time.

First, I want to apologize for the double post the other day. I, for
some reason, had forgotten that I'd already posted the day before.

Anyway, my situation is much better. I am able to capture japanTV. The
thing is that I'm not sure how. Here is what I did.

1) Connected the tuner card's analog side to the cable box/set-top-box.

2) Set the cable box to japanTV (in this case, channel 674)

3) Attempted to gather channels at mythtv-setup, which it did . . . a
handful (16,17,18,19, etc).

4) Just to see what channels it claimed to have found, I started
recording 1 minute bits of each.

5) To my surprise, tuner card channels 17,18, and 19 captured japanTV
with varying degrees of quality (18 being the best).

So, for now I feel better because I can put this project down for a
while. I guess part of my confusion comes from the fact that I didn't
set the tuner channel like I would the TV (channel 3). Although,
japanTV seems to be the only thing getting though.
