no diseqc setup works stabel for me :(
Also the Full DiSEqC sequence from default diseqc.conf doesn't work
a few hours after reboot and sometime it doesn't work directly after
reboot.
But I can switch the channel with szap and get the TS stream from
/dev/dvb/adapter1/dvr0 every time, even vdr can't record I only stop vdr
and do not a reload of the driver.

I did some tests with szap:

o I can only get the TS stream with the default lnb type or -l UNIVERSAL
o if I use another lnb type like ENHANCED, I can switch, but don't get
  any data.
o The ioctls are the same if I use diseqc with vdr, but as I said
  before, I didn't get any data a few hours after reboot of the system,
  and sometime I didn't get any data directly after reboot.
o If I use szap, I can switch the channels and get the ts stream every
  time (via cat /dev/dvb/adapter1/dvr0 > /tmp/bla).
o the first status is 01 and it has no lock all others are 1f and it has
  a lock (as seen below).
o when I call szap the second time (with the same channel) the first
  status is 01 and then 1f, too.
o maybe vdr does have to wait a longer time ?

What lnb type vdr is using, when I enable diseqc in vdr menu ?
I can't configure any frequenz after activate diseqc.

Here the output from your patched szap:

video:/tmp/szap # ./szap -l UNIVERSAL -a 1 -r -c /etc/vdr/channels.conf -n 2
reading channels from file '/etc/vdr/channels.conf'
zapping to 2 'Das Erste;ARD':
