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?
