I think your problem may be similar to what I had at first.
My card (a technotrend dvb-c rev 2.1) woud not lock on to the channels, I
usualy had to try several times to get a lock.
My problems was fixed by some change in the dvb-kernel drivers, I think some
part of the dvb drivers asks the frontend to retune if it doesn't get a
lock, anyway after that change I always get a lock on the first try with
czap. I don't think this was a frontend problem

So I sugest that you upgrade your kernel and try the dvb-kernel drivers,
it's woth a try anyway.

I had more problems with my card, I had bad signal on some channels, if I
moved the card to a different computer the channel with bad signal changed.
I bought a better powersupply, a 350W instead of 300W, it looks like that
improved the signal a quit bit.
Some channels that previously was unwatchable now as zero uncorrectable
errors (unc=0 in czap) and better signal.

Some channels still have errors occasionally.
