If you look at UKTV's portfolio, Dave and GOLD are the valuable channels, but would anyone really miss W or Good Food?
UKTV may have been able to pressure the likes of TV Player into massive device restrictions, so that you can only watch their channels on an Android box, PC, phone or tablet, but if Virgin feel if the channels don't have the value they once have, it's their commercial decision to get rid of them if UKTV can't meet the agreement to distribute them on the platform.
Personally I watch some of them, but if I was a VM customer who enjoys their output, I'd subscribe to an IPTV service.
Until Ofcom finally get off their arse and bring in the rules regarding carriage that we the public need.
