Did you receive any response for your question; I am using enigma2 extreme with mgcamd133 and have the same issues; namely that I can record on one tuner and at the sametime watch another channel however trying to use the second tuner i.e. to record two programs at the sametime does not work correctly. I have read that it is better to use oscam/ vizcam. Currently I suffer from a lot of freezes also.
