Online Sources on 42PFL3507K

Hello,
first of all I'd like to thank the Serviio team for the cool software they produced and the forum they set up here.
I've worked through the internez for three days now and decided to go to a professional

What I tried to get working is Desktop stream to my TV.
It took me quite a while to get the Stream running (especially with mpeg2 and audio working) but I think I have this part now, but online sources don't seem to play properly.

So far I used the normal Philips profile.
Normal video files play just fine.

I tried to access any Online Source afterwards. Especially I tried the following which I found on a wiki site of yours which I now can't seam to find again:

mmsh://live1.wm.skynews.servecast.net/s ... z_live300k
rtmp://cdn.rtmp1.yupptv.tv:1935/nwk/ swfUrl=http://cdn.freedocast.com/player-octo/yume/v5/infinite-hd-player-FREEDOCAST.SWF pageURL=http://www.yupptv.com/streams/newsx1.aspx playpath=newsx

and also one youtube feed.

For the two streams I get sound, but no picture.
For the youtube stuff my TV tells me after some loading time that the data format is not supported (which is btw the same error I got when trying to use my own desktop stream)

I also tried retreiving information about my TV via Device Spy, but my TV doesn't show up there. Also I tried the profile that was posted here: viewtopic.php?f=27&t=7669

unfortunately my log file is already 7 mb big and I'm not sure which information is really relevant; I tried to filter out what seamed to be not so relevant.

I'm thankful for any hint as one one side I'm already pretty pissed at this being so complicated and on the other hand don't want to get owned by my TV.
