Last week I installed yaVDR 0.5 in this machine, and... so far so good. Installation was easy and everything worked without problem, even remote control.
Everithing goes right, no hungs up. Softhddevice seems to behave better whit channels with low level of signal and no hungs in a week. I hope it keeps working fine.
I will wait a couple of weeks, and, if no hungs, I will change the subject to solved.
Regards, thanks and congratulations for your work with yaVDR.
