Hm, I never heard of that kind of problem. With some versions of
the frontend code I had problems during live view with my
DVB-C cards, but they are fixed now. Also, since you say
recordings are OK the frontend cannot be the problem.

How often do the glitches happen? On which
satellites/tranponders/services?

There are problems for the ves1x93 frontend, where the DiSEqC signals
are generated in the av7110 firmware. The timing is too inaccurate,
especially with hw_sections=1. The default for hw_sections is now 0
anyway, because the firmware does not perform crc checks.

Well, I have to admit the linuxtv.org website is a mess :-(
But I'm sure it was announce on the list that "DVB" CVS is dead,
and only dvb-kernel will be maintained.
