Field orders for DVD MPEG files

[beadie the dragon]

I am encoding some analoge files captured from an MJPEG capture card (G400-TV). The field order seems to alternate between upper and lower for individual clips (quality).

Now when I do the MPEG2 encoding I have to choose the field order acording to the original source.

Therefore, the final DVD will have a mixture of upper and lower field order MPEG files.

Can a DVD cope with different field orders on the same disc ?

Alternatively if I render them all as no field (progressive) what will it play back like on a TV (i.e. interlaced) ? Will the DVD add interlacing ?

I am in PAL land if that makes any difference and am using Vegas Video 3 to encode. I will use Maestro for the DVD authoring.

Field order can be mixed as the ordering is actually encoded in the MPG file itself, so you could conceivably even mix ordering within the same MPG file.

You can render as progressive frames, but you'd have to render at 23.976fps and set your MPG encoder (such as TMPGEnc) to add 3:2 pulldown on playback which would create the interlace frames.
