I believe this to be a drive limitation not Vista, if not I stand corrected.
No doubt someone will respond.
I recently both HP dv7 1270 model with Vista64 Home Ultimate O.S. I also have older HP dv7 XP, P4, with a media center on which I can play back any DVD from ANY region. The older media center recognize a
DVD and play the DVD regardless if it is recorded in PAL or from any region. The new Vista with the media center tells me that I must
switch to region (2) and that I can do it ONLY 4 times. I do not know what
it excactly means. I would like to play as many DVDs from ANY regions
on my new computer and as many times as I can do on my older loptop with XP. Can you tell me what can I do to achieve that? Thank you very much.
