BBC One HD is testing in some areas on Virgin Media. Channel scheduled to launch in around a month. BBC HD will subsequently screen programming from BBC 2, 3, 4, CBeebies and CBBC. May include some BBC News programmes too.
Incidentally, Virgin Media's Q3 results are at the end of the month: expect announcements of service improvements over the next couple of weeks as a precursor. ITV 2, 3 and 4 HD? TiVo? A 1Tb V+ ? Sky Atlantic carriage? Sky Arts HD? Sky News HD? 100mb home broadband? Anyone's guess.
