Recently my Humax PVT9200T has started to hang. When I started it up, within a minute or two (usually much less) the picture froze. Prior to this it had been working fine for the six months I had owned it. This seems to be a common problem for the PVT9200T of late, there is much talk of a patch on the way.
For me the immediate solution seems to have been simpler; I just reset it to factory defaults and let it rescan the channels. It has now been working fine for a couple of days. Maybe this simple solution will help other owners of the PVT9200T
