After sleeping over this for a night I tend to follow your idea of using modifed
names directly, thus having them appear everywhere.
I won't change these names in channels.conf, though (this file shall always
store what comes from the broadcaster - provided it is enabled in the setup).
- Make a setup option to "Show channel names with source" (default is "no").
- Modify cChannel::Name() and cChannel::ShortName() to optionally
append the source character (A, C, S, T, I, ...) to the channel name
in the (short) form mentioned above.
The attached patch implements this (i18n stuff left out for brevity).
Please give it a try.
@Ludi: BTW: in order to give you credit in VDR's HISTORY/CONTRIBUTORS file I'll
need your full name.
