I just noticed last night that virgin are now doing the ITV 23+4 in HD.
I don't know when it started but I am glad they are

I have VM, but only M+ pack plus Sports.
So I don't think I get ITV2,3,4 in HD.
But ITV3 in particular is a lot of old material that was not produced
in HD. I expect my TV will do almost as good a job of the upscaling.

ITV4HD is a pretty good one to get in HD - it has a lot of live sports
(French Tennis Open, Tour de France etc) which look SO much better!

It might, but the SD versions of those channels will be coded at significantly
lower bit rates, (and primitive old MPEG2) so you'll see far more artefacts,
than taking the uncompressed 270 Mb/s feeds at the broadcaster, upscalling to
HD, and encoding at HD bit rates (and modern coding systems)

You'd be mad to watch any channel's SD version, if you can receive the HD
version, regardless whether the source material is native SD or HD.

I take your point that the transmissions of ITV2,3,4 in SD are very
bit rate limited to start with.
Actually, a good studio picture from BBC1 SD looks terrific at normal
viewing distances on my Sony, Freeview-HD 100Hz TV.
I don't know if VM feed from satellite or Freeview for ITV2,3,4 SD. I
suppose HD must be transcoded from satellite.

I have the same TV, BBC 1 SD is vastly inferior to SD programmes, up converted
to HD, and viewed on BBC 1 HD. Why would you watch anything, (other than the
English regional news) on BBC 1 SD, if you have BBC 1 HD available to you ?

Something an old fellow said to me in 1970 or thereabouts. "I don't
listen on VHF. It doesn't sound right when you're used to the ordinary
wireless."

Yes. I'm used to the ordinary analogue, with fuzzy pictures, ghosting
and snow. All this blocky stuff looks wrong to me.
