firstly apologies if this is in the wrong sub forum, but unsure where else it fits.
I've got masses of DVD's that i've backed up to my portable hard drive so i can play them on my pc. but these no longer seem to play in NERO showtime or windows media player (I'm sure they did at some point)
the files were ripped using dvd shrink into an ISO format, but in nero i now get a message ' error reading file' when trying to open them in showtime
i can still view the file by opening disc image in dvd shrink and still burns and plays ok, just problems playing on my pc
thanks in advance
