I took another dive into the tuning problem. It turns out I can tune to any
channel with a patched svn 7185 (dvbchannel-v5). However, it seems I cannot 
subsequently tune to two channels on the first diseqc port (even if they
are on a different transponder!). If I switch from the first port to a channel 
on the second, I can actually tune to any channel on the first port that I 
like. Even the channel I reported this morning not to work. I can switch 
between different channels on the second port. If I force a reset in the 
Tune code

bool DVBChannel::Tune(const dvb_channel_t& channel, bool force_reset)
{
    force_reset = true;
    if (fd_frontend < 0)
    {

then tuning seems to work flawlessly. I noticed that the low/high band
offset in the current svn version is actually fixed in the dvbchannel-v5
patch, so sorry about the noise there. It puzzles me what messes around
with the tuner. Tried not to invoke the handle_diseq call when tuning is
not necessary, but to no avail. 

Best,
