Hi all, I have a Humax PVR 3000T… It records ok sometimes but it often records a show were the picture is really scrambled.. I tried to re tune all the stations but has not done anything.. so i was wondering if a firmware update might help as I have not done that ever.. I am pretty old so be kind.. were can i find the firmware updates for that model to download ? please.. or if you might think something else is causing it.. the tv works fine only when recording,
