4.7GB explodes to 22.3GB with Nero

eed help::
i purchased DVDs from Asia and they are encoded in PAL. My Sony player refuses to play in USA with an error “CANNOT PLAY WITH REGION RESTRICTION”. I tried finding region hacks but couldn’t locate one so decided to reencode to NTSC using Nero 6.0. But now Nero explodes the 4.7GB data to 22.7GB before transcoding.

Any help or clues would be welcome as i have got lots of DVDs to convert. Have already wasted 6 DVDs.

What DVD player do you use?

Sony DVP NS75H

Please don’t double post. :cop:
