C4's CatchUp on Virgin service on the V6 boxes is now thirty days of HD goodness. All of the C4 boxsets are in full HD too.
I still don't know if the shows on the new All 4 app on the V6 are in HD - does anybody? The catalogue in the app is far more extensive than the Virgin On Demand service but still has a few notable exceptions (Scrubs and ER). Good to see that the Seinfeld episodes are all in widescreen although they look like SD to my eyes.
