Hi!
In my country (and in other exUSSR-countries) TV operators use two
standards: SECAM and PAL.
In current freevo configuration I can select only one standard for all
channels.
My patch add feature in freevo for using second TV standard for the list
of selected freq's with switching to other standard. See example in
local_conf.py.example.
