It was quite not appreciable on my part to provide a fix or reply in
time nor spend much time on it earlier, but that said i was quite
stuck up with some other things.

Can you please pull a copy of the multiproto tree
http://jusst.de/hg/multiproto or the v4l-dvb tree from
http://jusst.de/hg/v4l-dvb

and apply the following patch and comment what your result is ?
Before applying please do check whether you still have the issues.

Manu,
I've tried to increase those timers long ago when played around with my card (Twinhan 1041) and scan utility.
I must say that I've concentrated mostly on DVB-S channels that wasn't always locking.
I didn't notice much improvements. The thing that did help was increasing the resolution of scan zigzags.
I've sent a patch on that ML and people were happy with the results.
The patch went to Igor's repository, don't know were it goes from there.

I believe DVB-S2 lock suffer from the same problem, but in that case the zigzag is done in the chip and not in the driver.
Since I have no documentation of the chip I was stuck and left it. So if you have the knowledge or documentation of the chip,
try to go in that direction.

By the way, question to those who have such channels:
Does windows based applications show those channels properly?

BTW: lot of patience you have compared to the other users :)

Regards,
Manu
