ETVS Channels on Virgin Media

I woke up this morning to find that my Virgin box had had a bit of a fit during the night and all the channels were screwed up! I couldn't watch any of the normal channels and the only ones I could watch were ones that are presumably hidden. What are these channels and what could have caused them to appear this morning?

ETVS10 had a repeated announcement stating "Three zero audio one", ETVS11 had sound but ETVS13 and ETVS14 were silent.

Video Clip

I'm guessing these are the interactive video streams. You're seeing the Open Golf stream and Big Brother live stream. The others with slides just won't be needed at present.

EDIT: As for the audio, they could doing testing for BBCi's alternative commentary programming for sport etc. The other audio stream will say "3-0 Audio 2". They do these tests on Freeview BBCi channels all the time.

Speaking of Virgin Media, is anybody having trouble watching a programme on teleport replay? It's says it's unable to do it anybody else having the same?

I'd say something to do with the BBC - I've seen that testing loop before on the streams on Freeview.
