To be honest the mediacentre has been rejected for TV watching for a long time (blame mysky, HTPC mainly movies + file server), ive just had it recording a series for future archiving and not watching.
But yesterday i was watching a program from the timeshift and i noticed i get glitches every now and then. Sometimes its very frequent, up to 3 times in 10s. Sometimes it'll go fine for 5mins before a glitch.
Also the magnitude of them changes, sometimes the audio continues and the picture freezes for a second, sometimes you loose audio and the picture goes blocky and unrecognisable for several seconds.
The iDTV upstairs has zero issues with reception. Setup is a 91 element UHF which i know isn't aligned correctly (its facing upwards slightly and to the left too much, need an extended ladder to reach it), then to a masthead amp combining with VHF, through the power injector to a splitter, which then runs to each room. Minimum of RG6 dual shield, quad shield between the wall and HVR-2200. In between the tuner and 8500GT theres a plastic bag with tinfoil 2-3 thick, to block out RF interference.
Thoughts? Is it the badly aligned antenna, even though the other TV has zero issues?
