Some different DREcrypt based systems need special handling

Description
problem description:
im starting to watch channel, after ~30 second video stops un after 10 second on debug screen message "webui: Timeout waiting for packets" comes.
after that im unable to open channel at all
if i restart tvheadend then i can watch again for a short period (20-40 seconds) and then problem starts again, sometimes tvheadend restart doesn't help.
Channel is H264 non HD, just a simple SD channel on H264 codec (dvb-s2), and satellite is EutelsatW4 at 36E on circular polarization
channels on other satellite with horizontal or vertical polarization dvb-s or dvb-s2 works fine

Updated by i solved my problem by commenting out line 311 in psi.c
changed
provid = size < 4 ? 0 : buffer[4];
to
// provid = size < 4 ? 0 : buffer[4];
looks like it was related to incorect handling of DRECrypt
maybe you can include this fix in new release of tvheadend

I need to discuss this with the original submitter of that chunk of code, they obviously added it for a reason.

Can you please check (or tell me) what the value of caid is for your provider? The exception there was added as Bulcrypt doesn't follow the same pattern of DREcrypt it may be the same for your provider.

I think possibly we just need an additional exception in the descrambler method detection. But we really lack expertise in this area and its difficult to test. Basically the best I can do is make the change and see if people complain I've broken other stuff 
This won't be able to go into 3.2 now, but I might push a mod to 3.3-dev and see what happens.

Not sure that title is quite right, I've forgotten the details. But its better than the old title.

Updated by Adam, can this feature be incorporated?
It really brings a lot of pain to us Tricolor users.
Attached patch seems to work
