Actually both syntaxes seem to work ;-) As the parser does not 
discriminate between them.

Bummer ;-)

I am testing the new DVB input on my own devellopment machine and have 
it running for over 4 hrs in a row without crashes. I think the 
crash/segmentation fault is solved now. The bad news is I didnot commit 
it yet to the CVS and on monday I'll be back at the office.

Can you wait that long ? Or should I try to remember what changes I made?

I just remembered that a diff against the archive got send on this list 
by me. Try this patch to modules/access/dvb/access.c and build the thing 
from fresh please. It has bitten me already a lot of times ;-( if I did 
not do that.

This should be fixed now but ... see above. Try the patch and report if 
it works for you too!
