Morning all, first ever post so please be gentle . I've had my 42PV500CAB / DMREH50 duo since last Thursday (next day delivery £2,350 Gultronics.co.uk). All is well and I'm very pleased with the picture overall. I was fiddling, as you do, and plugged in my old Daewoo Freeview box to the EH50 and to the screen via component. Flipping back and forth (even capturing at highest quality on the HDD recorder) I noticed that the picture from the built in DVB is noticeably less sharp even a bit fuzzier than my trusty Daewoo. I'd have thought the absence of cables/interference etc. would give a better PQ from the built in tuner. Has anyone else compared the PV500's DVB with external tuners? Also can anyone give me a run-down the recommended running-in tips? I'm currently viewing all channels in cinema mode with none of the NR options enabled. Any more I can do? I'm also looking to test the HDness of the screen and wondered how best to do this. I have an xbox, Laptop with HD clips off wmvhd.com and the EH50. Cheers for any input.
