... But diseqc positioner commands (GotoX from vdr rotor plugin) seem to not get through with 100% reliability. Changing to use diseqc.conf seemed to help a bit but I haven't been able to convince the motor to turn to 28.2E at all.
Did you try changing line 250 in mantis_dvb.c to:
if (!lnbp21_attach(mantis->fe, &mantis->adapter, LNBP21_PCL, LNBP21_ISEL)) {

I tried mantis-a9ecd19a37c9. Without the change success in positioning was about 0% similarly as with multiproto-0448e5a6d8a6. After this change the success in zapping between different satellite positions increased to about 40% so it looks now promising and vdr satellite channels are usable with some patience :^)
Is there some kind of soft-diseqc bit timing used with this DVB-S2 card or driver SW (I didn't yet look at the source) or why is the operation so unreliable? I had to use command duplication in vdr-rotor plugin with my old card but with that it was about 100% reliable.
Which DVB-S2 multiproto driver tree should I follow for latest development for TT S2-3200 (/Skystar HD)?
Cheers,
Seppo

You mean the LNBP21 attach line improved things for you by 40% ?

If you can really identify what is "really" unreliable, that itself will be a help
to fix the issue, in most cases.

For the SAA7146 based cards, use the multiproto tree, for the Mantis based cards, use the mantis tree.

Manu

Yes, the LNBP21_PCL and LNBP21_ISEL additions did the improvement. By 40% I mean that about 4/10 zappings between channels in different satellite positions are succesfull. Without this change it was very rare to get the dish to move, the success rate was < 1/10.

Compared to my old DVB-S card this DVB-S2 card is too unreliable for my family to use it. There is one possible issue with vdr rotor plugin. It would help in my case if it would set always high LNB voltage before sending gotox command and keep it for estimated time of movent (based on about 0.9 seconds/degree speed) before setting the voltage for the tuned channel. The motor movement with low LNB voltage is very slow especially in winter and I'm not absolutely sure that the failure is due to corrupted diseqc gotox command or just too low voltage to get the motor running. The old DVB-S card was also driving the dish at slow speed with low LNB voltage but I need to hack the rotor code to rule out this theory. I need to check also the LNB cable that connects to the PC that it is still OK.

OK, thanks. It seems there is now 10min fresh new code to try!

Now I've run original multiproto-8db34ae061ed driver for a day. It achives about similar success (my guess 40%) in driving my positioner motor as the edited mantis tree driver. As far as I understand the code the lnbp21_attach in ttpci/budget-ci.c is different from Simeon's proposed attach command for mantis. => I hope my comments are not confusing the development.
Excluding driving/commanding the motor, the current multiproto driver works well in DVB-S/DVB-S2 (and 2xDVB-T) zapping.

Seppo
