replica title

[Gruff]

Please excuse my naivety as I'm a relatively new player in the world of digital video. When I copy a dvd to my hard drive I get 2 identical vob titles which 'strobe' very slightly if played as a singlre track. The same happens if I import the disc in nero. It doesn't matter if it's pre recorded or one I've recorded from air on my Panasonic DVD recoreder. Is there a setting I'm missing somewhere possibly? I'd be very greatful for any help, it's driving me mad!

are both files the same size ? also see if there is a fluu screen & a wide screen version on disc.

pardon the spelling *Full Screen / Wide Screen

Both ex\cltly the same size and same aspect ratio, bizarre!
