Hi all I have a Samsung BD-DT7800 PVR and seem to be having issues with what I believe is the bit error level causing the picture/sound to break up on some channels, eventually leading to a 'Weak/No Signal' message being displayed. This does not happen on all channels though. It only seems to happen mainly on the HD channels, channel 303 and The Space (all under frequency 738000KHz and the same multiplex). When looking at the 'Signal Information' pop-up, the signal strength is always 100; however, the bit error level fluctuates between around 1000 and 2000 (maximum) - it seems that when the bit error level stays at 2000 for more than a few seconds, the signal cuts out. The other thing to note would be this isn't always a problem. Sometimes the bit error level can hover around 1000 for a few hours and show no visible interference; yet other times I can barely watch anything on those channels. I've read through a lot of posts on various forums and blogs and have tried removing items that could be causing interference, relocating the TV, using the PVR on a different TV, using a different coax cable, not crossing over the coax cable with the HDMI cable, re-tuning (both manual and auto) and factory restoring the PVR but have had no joy whatsoever. I live in apartments so haven't been able to investigate anything to do with the ariel at present. I've also checked the Freeview websites and I should have perfectly fine coverage for the area I live in. Does anybody have any ideas what else I can do? Thank you!
