"dvb-kernel" internally uses Video4Linux-2. I suppose you are using 
Video4Linux-1 -- all these command will go through a compatiblity layer, 
which does it's best to match the commands.

But especially capturing is very differnt, so sometimes it simply fails.
I'll install "kvdr" and see what happens behind the scenes.

The dvb-backend is supposed to be the same, all bugfixes are done both 
in "DVB" and "dvb-kernel", the same goes for bugfixes in the av7110 
driver for example.

Only *new* drivers and really experimental stuff is done in "dvb-kernel" 
only.  For example, I have changed the underlying saa7146 subsystem in 
there, which now supports Video4Linux-2. But this should only effect 
video output via /dev/video (as you are experiencing now) and not the 
way the dvb driver work.

Regarding your module version problem: I've never used the option, 
because I'm recompiling and adding modules and stuff to my kernel build 
quite regularly. Although these options should make this easier, for me 
it happens quite often that I cannot load modules from an earlier kernel 
build anymore, because the suffixes have changed.

Doing a "make modules_install" erases my modules directory, too. This 
has changed somewhere between 2.4.18 and 2.4.20 IMHO.

CU
Michael.
