Hi (Mauro),
below you will find my recommended patch for the broken
VDR format (libdvbv5/dvb-vdr-format.c).
There is only one point I have a doubt: I have no ATSC
experience (I'am in Europe/germ), so I simply added
an "A" at the field "satellite pos.". This is what
the w_scan tool does and this tool works fine with
the vdr (please correct me if I'am wrong).
My test-case was the same as mentioned in the first
mail (see below). Which means, I haven't tested with
vdr, only with mpv.
Is there anyone how can take up this patch?
... may be Mauro, the originator of vdr support?
With best regards
