Regards Dimes' policy.
That's probably the most ridiculous thing I've ever heard - who makes this rubbish up?
There are plenty of official DVDs on the merketplace that use ac3 sound and not PCM, and have programme content that lasts longer than 60 minutes.
Dime's policy would suggest that (were official items allowed on their site), they'd filter out any that use ac3 sound????
That's even more stupid than removing 3 songs from an unreleased unnofficial concert because those 3 songs were released officially on a compilation.
