Yes, the module saa7134 must be loaded, otherwise you won't even have a video
device. But they don't need to be loaded at boot time, you can load and unload
them whenever you like, as long as no application accesses the devices.
Did you try to load the sa7134-dvb module while a tv application is
running? With some cards the is dangerous because it can cause a collision
on a cards internal bus. This can crash the card (only the card) so badly, that
you need a power cycle to get it up again.

I think you don't.
Please get a snapshot from http://www.linuxtv.org
This gives yo a recent driver.
After you unpacked the snapshot, do a
make, make install, make rmmod
to be sure, do also a
for most of the commands, you need to be root.

If you need further help, don't forget to attach the relevant section
of the kernel log (either dmesg or the relevant part of /var/log/messages)
