In Germany Tele5 is showing VOY and TNG in HD. ZDF_neo is showing TOS in SD but from the HD masters. Both Free-TV channels. ENT and the movies are on Pay-TV. DS9 is currently not showing (but was on Tele5, like ENT).
Why would ZDFneo show TOS in SD? It's an HD channel, so I would assume that it's showing TOS in HD!
I wouldn't be so sure about TELE 5, though ... they are only HD through Pay TV, the free version is SD.
