Reauthoring Reg 2 Discs

A few questions on one of my sideline interests.

I'm a huge Anthony Hopkins fan and am anxious to acquire some of his old films that have only been released in Europe as Region 2 DVDs. SInce these films are very unlikely to be released as Region 1 discs, I thought I would bite the bullet, buy the foreign discs (at a premium price, no doubt) and then, if possible, rip and reauthor them myself as region 1 discs so that I can watch them on my home player and TV (personal use ONLY).

There are actually two categories of material at issue here. One is comprised of stuff that was originally shot on film at standard 24 fps. The other is BBC and other material that originated on PAL video for broadcast in England and Europe.

Assuming I temporarily change the region of one of my DVD drives to a region 2 drive and acquire the appropriate ripping tools to extract the vob files from these discs, will I be able to reauthor the discs as region 1 discs that will play in native region 1 players that are feeding NTSC 29.97 fps televisions? Will the process be different depending upon the original source material (film vs. PAL video)?

Since film starts out at the same frame rate no matter what the destination format or TV system, I'm assuming there's no reason a reauthor of film material can't be done for region 1. Some ripping tests I did yesterday on a region 1 commercial disk with film-originated material show that the extracted file has a frame rate of "23.976" IVTC. I assume this means that, regardless of region, filmed material is filed on the disc at a standard frame rate and then the proper pulldown/rate adjustment is applied by the player (NTSC 29.97 or PAL 25, depending upon the player's region) during playback. Is this correct? Will I be able to leave the extracted mpeg2 files in tact and simply reauthor an NTSC compatible disc from them without re-encoding?

I'm much less sure about the process for PAL video-originated material. Would I be able to author an NTSC compatible disc from in-tact vob/mpeg2 files that were extracted from a region 2 disc of 25 fps PAL material? Is there a standard, in other words, within the DVD specification for players adding appropriate pulldown for PAL material to be viewed on NTSC displays? Or would I have to convert the vob/mpeg2s to AVIs, bring them into a Vegas project that uses an NTSC frame rate, where appropriate pulldown can be applied, and then re-encode everything to mpeg2 and author based on the new renders?

I have never worked with PAL video EVER and really don't know much about how the DVD standard works to coordinate the differing world frame rates in video and film. So I feel very ignorant about how I might attempt this process. Much appreciation for any help.

The most Home DVD Players can set output system to choosen by user, look in players manual. If it can do this, symply rip disks using DVD Decrypter (http://www.dvddecrypter.com/) to HDD and burn to another DVD.

I can’t answer all your questions, but I can take the easy ones..

If you “rip” and reauthor, you won’t have any issues with region code. Any disc you author will be region free. There are copyright issues in doing this, even if it is for personal use, but I assume you know that.

Converting from PAL to NTSC can also be done, see
PAL-NTSC conversion

What I don’t know for sure about is your questions about films and if a conversion can be avoided, but I don’t think this is correct. I know that in general a NTSC player generally won’t play a PAL DVD (though some will), even if it is multi-region and the source was film. As well as frame rate there is size; PAL is 720x576, NTSC is 720x480.
