Samsung LE32D551 file not supported error

I´ve tried everything I know to get this stream to work on my TV but the answers I´ve found here on the forums are incomplete. I´ve tried adding maxVBitrate=30000 to the video group of Online Transcoding but it doesn´t help.
I´ve got a clean install of serviio on Windows 7, the latest ffmpeg on the machine, the profile is set to the Samsung C/D profile and I can play my media files without problem on my TV over the network. However, as soon as I add
"rtmp://ruvruverllivefs.fplive.net/ruvruverllive-live/stream1 live=1" to the online sources and try to play it, it kicks off fine, plays for 1 or 2 minutes and then stops, giving me the "file not supported" error.
Can anyone suggest what I´m missing?
This is what I get when I ffprobe the source:
