george,sven,ch, thanks for the information about the differences.i live in a technologically deprived area.i received 1 channel on the telly for 20 years before investing in a satellite system.now ,as bruce springsteen sang"54 channels and there's nothing on" guess we"ll try to return the videos or go to the uk and watch them.i like the second option.a tall frosty pint of watney's red ale and a good video sounds good!
