i discovered that issue also and started to discuss it on irc with manu and andrew.
therefore the
[PATCH] Multi protocol support
thread was started on 12.04.2006.
while manu is developing a dvb-s2 driver, those things mentioned within that thread,
were discussed and i stopped working on my patch for a while.

ok, blame me, but if an app is ported to use FE_SET_FRONTEND2 it should
_not_ still mix with FE_SET_FRONTEND calls.
i'll explain more on my next reply to your mails.

done.
