Hello,
Is this the right place to ask for such help/questions?
at least I d like to understand where this issue comes from (myself, the signal
or the config of MythTV)
Merci
XabiX

Objet : h264 HD channels not visible correcty
Hello,
I am wondering if I can't see HD channels correctly because of a bad reception
or because of a configuration issue. I can see non HD channels with no problem.
I got a Signal of 44% and a SNR s/d of 2.1db. Ex:

I am using the XvMC Standard decoder and the following intel integrated video

Any idea of what could be the issue?
Thanks
