Thanks for the heads-up. I've just installed KMPlayer and WorldTV99 on my N900 (haven't installed mplayer). It sort of works but isn't quite ready for prime time yet.

The KMPlayer UI is, well, perfectible. But it's still usable.

I opened the France folder and tried to play the first station, France BFM TV over wifi. It buffered for a couple of seconds and then played for about 5 seconds. The video quality was excellent. But then it stopped playing without any explanation.

I then tried to play the second french station, France 24 eng. It didn't play and instead it started to scroll though all the stations in the France folder, failing to play them all. It stopped scrolling when it reached the last station in the folder. So I tried to play the first station again (BFM TV) which had worked fine just a few seconds earlier but it failed to play it and instead went into its mad scrolling thing - trying to play every station in the France folder and failing to play any of them.

KMPlayer then completely froze for about a minute. Once it got defrosted, I tried to play BFM TV again and, this time, it played fine.

I closed KMPlayer and relaunched it. Opened the France folder again and played BFM TV again. It worked. The Pause button didn't work though. Pressing Pause caused the button to turn into a Play button but the video kept playing nonetheless.

So I closed KMPlayer again. After having closed it, the hildon-thumbnailerd process went completely mental and started to use up 100% of the CPU - killing my battery in the space of a few minutes (only had a third or a quarter of the charge left to start with). That could be unrelated to KMPlayer though - not sure (come to think of it, I took a screenshot of KMPlayer while it was running so maybe the thumbnailer daemon is related to this instead).
