Yep that's also one thing that I tried. I had them set to 6s and 10s
respectively which didn't happened at all, it just made scanning the whole
channel range last longer.

Any other ideas? I'll try 0.25-fixes tonight if I have some time, I've read
the LiveTV has been much improved in this release.

Thanks,
Igor
