[vdr] RFE: Make VDR more friendly when using combinations of DVB-S, DVB-T and DVB-C

Hello, 

Some time ago, I started a discussion in german on the VDR forum about
making the VDR more friendly for users that are simultaneously using
different sources to receive channels: 
http://www.vdr-portal.de/board16-video-disk-recorder/board8-vdr-grundlagen/110156-%C3%BCberlegungen-zur-channels-conf-f%C3%BCr-dvb-c-s-t-mischbetrieb/index3.html

I am going to explain the problem, when receiving channels from two
different sources by using the second german public channel named ZDF:

Suppose a user is receiving the channel ZDF by dvb-s and dvb-t. For the
VDR, these are two different channels, and it probably is not a bad
thing that the VDR differentiates between them because these channels
might be of different quality (different data rates, etc.). However, as
both sources name these channels often the same way, it is not easily
possible to differentiate between the two channels in the VDR OSD,
which is particularly annoying for the timers, one of the main VDR
features. 

Currently, I work around this problem, by setting the VDR to not update
channelnames and manually adding a suffix to the channelnames in the
channels.conf. So, to use the example above and differentiate between
the two channels, they could be renamed to ZDF-s and ZDF-t (or ZDF.s
and ZDF.t, or...). In practice, I only only rename the channelnames of
the source with the smallest number of channels; I know that the
channelnames without suffix are those from the other source. 

@ Klaus

Do you think that you could add an additional option to one of your
next VDR releases, like "Add suffix about source to channelnames"; I
could imagine such an option next to the "Update channels" option in
the DVB section of the Setup in the OSD of the VDR. 

Since the information is already in the channels.conf for every
channel, I assume, that it will not require huge changes to the VDR
code to use channelnames-source (or something similar) instead of only
the channelname in the channelname field of the channels.conf, when the
corresponding option is active. 

In case, I am missing something, I would also like to ask everybody
reading this to let us know, if for any reason, the idea about
replacing the channelnames with channelname-source cannot work. 

There are of course also other solutions, like adding a system to the
VDR allowing the user to indicate to the VDR, that both ZDF channels
(to continue with the example above) are only variations of the same
channel; the VDR could thus only show one of the two channels in his
channellist (hd channels could also be seen as another variation of the
channel); a priority system would be required to indicate what
variation of the channel to use for recordings,... 

Restarting the discussion about how to best handle the simultaneous
reception of more than one source is on my ToDo list since I started
that thread in the german forum. Unfortunately, I did not have the time
to do it until now, and probably will not have the time to do it
seriously in the near future. Moreover, since I got the idea about
simply adding the information about the source to the string of the
channelname, I decided to ask for it, instead of waiting for something,
that would probably require a long time to get designed and
implemented. 

Cheers,
