[mythtv-users] Channel tuning broken in 0.24

[Igor Cicimov]

Hi all,

I noticed that after upgrade to Mythtv 0.24 the channel tuning is awful.
I'm using Leadtek DVB-T DTV2000H (using the digital receiver only) and the
card was working fine for years on 0.20 and later for couple of months on
0.23-fixes. After upgrade to 0.24-fixes it can't scan half of the DVB-T
channels in Sydney and recording on it is practically impossible. The
distro is Mythbuntu 10.04 with the latest kernel from the repo (which I
think is 2.6.35 but not sure I'm not at home now to check).

What has changed in Mythtv to affect this card so badly? Anything I can do
to improve the performance? And yes, I tried deleting all the
cards,inputs,sources etc in the backend and recreating again but no
changes. Or maybe the kernel driver cx88xx in the latest kernels does not
play good with this card any more?

Before rolling back to 0.23 I'll try to check the card performance outside
Mythtv. In meantime, any suggestions to solve this highly appreciated.

Thanks,
Igor
