[vdr] Update for NTSC problem

[Andrey Vlassov]

Vladimir,

I normally unload/load drivers before starting VDR but I never checked 
that all drivers have been unloaded.

I don't have full list drivers which related to DVB-S card to check what 
modules should be unloaded. I guess that if I will check list of modules 
which loaded with "./insmod.sh load" I should have this list.

Do you think that this list should be correct and I will not miss any 
important module?
