unfortunately, i think your complaint will not amount to anything. a lot of channels are struggling. several last year went online only. some have since disappeared. when you have the likes of bbc,itv,channel 4 and channel 5 all considering joining forces to provide a streaming service it shows how bad things are.
there are too many channels for the uk public who have found ever increasing alternatives in life be it other services or interests.
Oddly today some subtitles did appear on tv serials so its possible ZeeTV or virgin somehow switched on something, I do recall subtitles use to work on the old Zee tv SD channel but sometimes it was hit and miss or buggy.
I think ill give the zee stream service a bash with its 30 day free trial, it does feel everything is going to stream world.
