Great to hear I'm not crazy. :)

Yup I agree. It happens while tuning to analogue channels. No errors.
The picture is there and everything is ok.

This is what I get if I run "scan channel-list" for every frequency
scanned:
tda18271_read_regs: ERROR: i2c_transfer returned: -5
tda18271_ir_cal_init: error -5 on line 786
tda18271_init: error -5 on line 810
tda18271_tune: error -5 on line 831
tda18271_set_params: error -5 on line 912

And I think I narrowed it down to a DVB problem for now, since analogue
reception works in mplayer and vlc. I have yet to figure out why mythtv
refuses to cooperate. Seems to me it has something to do with the

"cx25840' 1-0044: 0x0000 is not a valid video input!"

message. This doesn't happen with vlc or mplayer.

I tried Windows XP. Both tuning is ok there (analogue and dvb-t).

Custom 2.6.28.8 kernel (with all the options in dvb and v4l section as
well as those listed on your driver page).

I tried them all (also ubuntu generics from jaunty which is also
2.6.28-something). Currently I'm running the latest one off your
web-site. I also tried 2.6.29-rc8 - no differences.

I also disabled lirc as suggested.
