I use to organize flash video streams (from YouTube and other sites) in playlists (m3u, pls or asx) so I can see them as a continuous stream, e.g. like this (m3u example):

#EXTM3U

http://v126.youtube.com/get_video?vi...4Caw7IIc&=.flv

Providing you have installed FLV splitter and ffdshow, you can watch this kind
of playlists with any DirectShow based player (I use WinAmp). The problems arise when I try to watch them with MediaPortal.

With My Videos:
MP by default display only M3U playlists. To display PLS ones, I have to manually insert the .pls extension in the recognized media list. But M3U don't start playing. A quick look at the log reveals why: it seems that MP considers any URI as relative, so it adds the path of the directory where the M3U is to the link
(e.g. C:\MyTube\http://ash-v75.ash.youtube.com/get_v...NCc56_0c&=.flv)
With PLS ones, instead, the stream start playing and audio is heard, but no video.
I've tried with My Radio: here MP displays ASX and PLS; the order of the streams is variously altered (by name, by channel, by bitrate but no way to get the original order) and, again, audio OK but no video.
I have to say that with MP 0.2.0.4 at least the PLS playlists worked fine.
