Glitchy HD Channels DM800HD

[mrblue]

Been having problems with a few hd channels since I got a dm800hd. ESPN HD I miss in particular & E4 HD

I bought an in line amp, it has made an improvement but the hd channels are still unwatchable plus the box makes a strange buzzing noise on these faulty channels.

I have the in line amp at the box end, maybe it should be closest to the dish...??

check your tuner
the latest one is rev M
sonds as if you have rev L installed
the inline amp helps a little but
the rev M tuner sorts out the problem
