Downloaded Theatertek last night for a 7 day trial .... I'm comparing with my existing player - PowerDVD XP 4.0 and I'm having real difficulty seeing any difference in picture quality. I'm using a Sony 12HT @ 1366x768x56hz and a 10' screen, so I would of thought any small improvements would show up on this setup? Can anyone suggest what I should look for? I know many of you have gone from PowerDVD to Theatertek and rave about the improvements, however at the moment I think I'll be requesting a refund rather than requesting my permanent registration key! Cheers p.s. can Theatertek play DVD's off the Hard drive like the CTRL+O option in PowerDVD?
