I hear you….We’ve done it in the past to save on replication costs.
No one will care about the extra lines of resolution….but then again, thats what is takes to be a professional so I agree and understand your point.
Can you post a sample of the issue youre seeing?
Here’s another thread to read:

Also remember that there is no true progressive in DVD….DVD is over 20 years old so it predates any progressive video technology Only interleaved fields.
i wish I had a definite answer but Ive done several PAL title years ago and they were all interlaced
From the Spec
A disc has one track (stream) of MPEG-2 constant bit rate (CBR) or variable bit rate (VBR) compressed digital video. A restricted version of MPEG-2 Main Profile at Main Level (MP@ML) is used. SP@ML is also supported. MPEG-1 CBR and VBR video is also allowed. 525/60 (NTSC, 29.97 interlaced frames/sec) and 625/50 (PAL/SECAM, 25 interlaced frames/sec) video display systems are expressly supported. Coded frame rates of 24 fps progressive from film, 25 fps interlaced from PAL video, and 29.97 fps interlaced from NTSC video are typical. MPEG-2 progressive_sequence is not allowed, but interlaced sequences can contain progressive pictures and progressive macroblocks. In the case of 24 fps source, the encoder embeds MPEG-2 repeat_first_field flags into the video stream to make the decoder either perform 2-3 pulldown for 60Hz NTSC displays (actually 59.94Hz) or 2-2 pulldown (with resulting 4% speedup) for 50Hz PAL/SECAM displays. In other words, the player doesn’t “know” what the encoded rate is, it simply follows the MPEG-2 encoder’s instructions to produce the predetermined display rate of 25 fps or 29.97 fps. This is one of the main reasons there are two kinds of discs, one for NTSC and one for PAL. (Very few players convert from PAL to NTSC or NTSC to PAL. See 1.19.)
Because film transfers for NTSC and PAL usually use the same coded picture rate (24 fps) but PAL resolution is higher, the PAL version takes more space on the disc. The raw increase before encoding is 20% (480 to 576), but the final result is closer to 15%, depending on encoder efficiency. This translates to an increase of 600 to 700 megabytes on PAL discs compared to NTSC discs.
It’s interesting to note that even interlaced source video can be rendered as progressive-structured MPEG pictures by a good encoder, with interlaced field-encoded macroblocks used only when needed for motion. Most film sources are encoded at 24 frames per second (the inverse telecine process during encoding removes duplicate 2-3 pulldown fields from the videotape source, and the remaining field pairs, although technically in interlaced form, can be re-interleaved by a progressive player). Most video sources are encoded at 25 or 30 interlaced frames per second. These may be mixed on the same disc, such as an interlaced-source logo followed by a progressive-source movie.

Maybe this link will shed some light:

Personally Id just make an NTSC 23.98 title and be done with it. NTSC discs are all over Europe.

I don’t use Encore but I can tell you those are pan scan menus.

DVD is a standard definition format. You’re going to get a loss of resolution when coming from HD….no way around this 🙂

Usually its your overall bitrates are too high and/or bad media
What are your avg bitrate settings? Also it’s a good idea to use AC3 audio since its compressed and takes up less bandwidth then AIFF

Hey Dan. Hold on
-
Better yet….send both folders on a pen drive
-
What’s the error?
Have you read the manual or looked on line for tutorials on setting the break point ( there are several) and are still having issues?
-
That’s weird….doesn’t Demuxer just give you the original m2v files? And audio?
Try opening the VTS FILES with Streamclip
-
Where are the original files? The master project? Best thing to do is start over.
Im confused since HD DVDs dont contain VOB files or VTS
