I'm using Mobile TV on a parallel imported E51, which seems to actually work!! (yay)

It will open the clip up in Real (c--p) Player, and seems to work OK mostly, however I seem to get a bit of buffering.  What do the NZ purchased handsets use to play Mobile TV?

Does it do this on local handsets too? I think my 3G coverage out here is OK, I get full bars by the looks. 

However I have noticed in the top right, it keeps flicking between 3.5G, 3G and something else, not sure why.
