I am at my witts end and I hope the problem I face is a solved problem
or at least someone has an idea what else I can try.
Gentoo Linux (22.214.171.124), PX-TV402U, MythTV (mythtv-0.20_p13053.ebuild,
I tried slightly oder ones from the 0.20 series too).
Since I'm in Japan, I selected japan-broadcast, and defined manually the
channels (e.g. 1 forNHK, 3 for their educational channel etc.). Those
numbers work well with gorecord.
gorecord works perfectly fine: setting channels, and recording from them
is a snap.
mythtv shows a picture, but it's not correctly tuned to the first
channel, however it's viewable.
When looking at the program guide, I also get the same TV picture
(smaller of course) in the upper right corner.
What does not work:
Changing channels. Recording from any channel except 1, which is
not really useful as the quality is so bad.
The Plextor unit it recognized nicely:

When trying to change channels I get
Mar 17 17:11:35 media go7007: unsupported ioctl -1069263306
quite often, which is harmless according to
And those I get whenever I try to change a channel:
Mar 19 21:10:59 media wis-sony-tuner: tuning to frequency 91.2500 (VHF_L)
Mar 19 21:11:34 media wis-sony-tuner: tuning to frequency 205.2500 (VHF_L)
Mar 19 21:12:09 media wis-sony-tuner: tuning to frequency 103.2500 (VHF_L)
I've never seen any other frequency, and I've tried all 10 configured channels.
On the screen it always showed the same badly tuned NHK channel 1.
It seems to me that MythTV cannot change channels, but I don't understand
why and how to fix it.
Anyone with an idea?
