Hello my mag 351 is freezing
Same issue here since the last firmware upgrade months ago, infomir does not help or respond at all.
Go back to the previous update and keep checking this page to see if any new Firmware has been released that has fixed the issue until then. Make sure "Software Autoupdate" is Deactivated until then. Its recommended only to update Firmware after successful conformation from other users here.
Lately it seems that the MAG 351 is missing some audio & video codecs. I got screen problem on some channels (very few to be honest) and audio problem (no audio) on some other.
Really time to get a fw update ;-)
