True Movies was owned by Sony, they renamed it Sony Movies Classic and changed the type of movies it shows. That's Sony's decision, not Virgin Media's, the same change happened to this Free-To-Air channel on Freeview, Freesat and Sky.
Most of the non-Sky-branded movie channels are Free-To-Air. You can get them via a rooftop aeriel or satellite dish for no subscription. The only non-Sky-branded ones are Movies24, Movies24+ and TCM which are Pay channels.
Hi the other route to consider buy an Amazon fire stick and subscribe to Amazon video and Netflix both of which have an excellent selection of films box sets etc, for less money than a sky cinema deal with virgin.Regards Micky
