Sound but no picture in Live TV/playback.

I think it may be a case of the stream type being reported incorrectly.

If you got to settings -> devices, double click your device, then double click a channel, what does it report the service type as? If you change it to h.264 then try watching the channel, does it help?

The previous version threw an exception when double-clicking channel.
I've upgraded to 2.5.9, and now dialog opens OK, and Service Type seems wrong.
But if I change it, it throws an exception.

I've documented this in attached .ZIP including full exception info.

Horray! After deleting all channels, and doing a rescan, the stream type is set correctly, and Live TV works!

The bug in the channel editor is still valid. If you try to save the channel, it throws an exception.
