I have a Humax HDR-Fox T2 connected to a Panasonic TV by HDMI cable
It has been working well for over a year but suddenly the HD has dropped to 576i.
I had previously noticed that unless I switched the PVR on a few seconds before the TV I occasionally would not get any sound. Other that that there was no warning of any problem.
I have just upgraded the software to 1.02.32 and tried another HDMI cable but neither has fixed the problem.
Any ideas?
