It's so frustrating that subtitles are not available on On Demand programmes. The only reason for it is that broadcasters aren't forced to make them available (the legislation doesn't cover digital programming since that hadn't even been thought of at the time!)
I hate the fact that I can't watch any of the programmes the rest of the family does, because for me not having subtitles is the equivalent of having no soundtrack.
If anyone else feels the same, Action on Hearing Loss have started a campaign to ask the Minister for Culture to deliver on his promise to review legislation.
