Description
Tuning to a "video only channel", this is a stream which only contains a VPID but no APID., Mediaportal eigther shows "No signal" or "No audio / video dedected" error message.
In DVBviewer no problem to tune to this channel and the DVBsource filter is indeed showing there is no audio.
Don't know if much has to be altered in the TV-server code. Maybe it is not so difficult to implement.
Mabye it could be helpfull to foresee an extra propertie like "only video channel" in the TV-channels list where the user can select this and the TV-server can be triggered by this propertie.

Steps to Reproduce:
Satellite: Astra 1 - 19.2 °E
Transponder: 12722000 H (symb: 22000, FEC: 3/4, MOD: 8PSK DVB-S2)
Provider: TV-Vlaanderen
Channel: Informatiekanaal --> FTA --> can be used to test !!!!

This channel is the providers information channel with some sheets in a loop.

    Hello again w8andc (I really like your forum handle! :D)

    So first, we can see there is no audio stream for this channel:
    2013-05-04 00:30:06.447132 [(18)]: subch:0 SetMpegPidMapping
    2013-05-04 00:30:06.447132 [(18)]: subch:0 pid:1FFE pcr
    2013-05-04 00:30:06.448132 [(18)]: subch:0 pid:146 pmt
    2013-05-04 00:30:06.448132 [(18)]: subch:0 pid:20E video type:MPEG-2
    2013-05-04 00:30:06.449132 [(18)]: subch:0 map pid:20E video type:MPEG-2

    As confirmed over -->here<--, TV Server (and probably MP as well) don't support video-only channels.
    I have added an issue in our bug-tracker:
    http://mantis.team-mediaportal.com/view.php?id=4421

    ...however, I do not expect that support for the feature will be added any time soon (there are too many more important bugs and features that must be completed, and not enough developers).

    Thanks,
    mm

    Thank you for picking this up ! ;)
    I appreciate the work of all developers even more if you see how many bugs are resolved in the bug-tracker list for the upcomming MP 1.4.0.
    MP is still a great multimedia solution for PC !
