Thank you for your work.
I now use the nightly and everything is fine with your update but RTSP still not work.
No problems using DVBViewer as a RTSP-Client.

Probably ffmpeg related. Try enabling debug log, enable RTSP, switch channel, open xbmc.log located in %appdata%\XBMC\userdata\ and search for "DVBViewer". You'll see something like:

Code:

PVRFile - Open - playback has started on filename pvr://channels/tv/All TV channels/<num>.pvr
DEBUG: CDVDInputStreamPVRManager::Open - stream opened: rtsp://<rtsp url>
[...]
DEBUG: ffmpeg: [rtsp]
