I spoke with Mark at Humax, St Albans this afternoon . He confirmed an earlier statement from Humax last month that there is a problem with the PVR9200T that is beig addressed by a software fix now under test. He thought it should be OK by the end of Feb, but in any case if the PVR is left on stand-by, there will be an automatic update/fix as soon as ready. For me the machine freezes as soon as switched on. Pity, because is has served us well for 4 years - it's a fine product and I gather this problem has arisen because of retuning at the digital switch time - although it didn't show itself to me immediately.
Unfortunately Humax didn't respond to a more recent email from me on the subject, although last month they did with a fuller explanation, saying a similar problem with the 9300 had been fixed and help was on the way for 9200s
