I can confirm that Gernot's patch 
http://pansy.at/gernot/twinhan-vp1041-3.diff.gz
is working for me for the Twinhan VP-1041
(aka Azurewave AD-SP 400, and it looks like the Technisat SkyStar HD2 too.)

Kernel 2.6.22 (ubuntu gutsy).

Scan found 1198 FTA TV and radio channels on Hotbird. Finds DVB-S and
DVB-S2 channels ok.

Tuning with szap -i -r working fine (still have the hanging problem with szap -r but interactive mode is ok).

DVB-S:
Tuning between channels in 2-7 seconds.
Playing fine with mplayer. Reception seems solid.

DVB-S2:
was able to tune and lock several DVB-S2 HD channels on Astra 19degE
(though not always first time). Dumped out a few files from ASTRA HD+ (FTA) 
-- when played with mplayer I hear the audio but see no video. Don't know 
if the files are actually ok yet. 

Many thanks Gernot.

Hans
