[linux-dvb] Skystar HD2 (device don't stream data).

Hi barry, good morning.

As you said, the file that I attached is too bigger than the limit of
the mailing list, so I uploadet it to
http://sites.google.com/site/bethnull/ , for someone that it will be
interested in, on this page there is a tgz file that holds ten scans
runs with the output and error redirected into two files
(channels_x.conf and channels_x.err).

As I said as soon as I arrive at home I will do some test on this
transponder, and make a dish realign.

Late but there are uploaded to http://sites.google.com/site/bethnull/

Sir Yes Sir :D, of course as I arrive home (on friday)

Doze? what does means?

Mamma mia :D

Ummm I know, and make sense as you said that the PMT data is
remembered from the last transponder.

Ummm, I understand, I thought that they were always "running".

Ok barry, as I said, I will do the "todo" list as soon as I get home.

Thanks for your kind support and best regards.
