The Prof 7301 arrived after 3 weeks (including New Year holiday) from Hongkong and fortunately went right through Canadian customs without any charges.
I've had a week to play with it and so far I have tried the following programs
Mytheatre:.... picture and sound but no motor control
DVBdream:..... fully supported, motor and all functions tried working.
ProgDVB:..... picture and sound and motor control working via positioner, couldn't set up motor to automatically move with channel change, yet. I didn't spend a lot of time on it as the free version doesn't support DVB-S2
DVBviewer:..... fully supported, motor and all functions tried working. Imports xmltv data for the EPG data easily, well worth the 15 euros its one of the most stable sat programs I have tried, my only problem at the moment is I have been unable to view signal strength and quality data while nudging the motor position, the may be a way but I haven't found it yet.
Motor control didn't work with the drivers supplied on the disc I had to download the 1.12 drivers
I don't have any way to measure performance but compared to my old Twinhan card I have the impression that sensitivity is improved, the card certainly holds a weak signal a lot better and channel changing is less than one second comparable to my Coolsat 5000.
I haven't been able to find many DVB-S2 signals to lock onto just LPB and OETA on AMC21 although that signals are only occasionally strong enough, it looks like a bigger dish is in my future.
