I'm using PPro 1.5 to edit my production, and exporting it via Adobe Media Encoder for authoring in ULead DWS2. The export settings from PPro that I've used are:

Codec: MainConcept MPEG Video
Quality: 5.0 (high quality)
TV Standard: NTSC
Frame Rate [fps]: 29.97 drop frame
Field Order: Lower
Aspect Ratio: 4:3
Frame Width [pixels]: 720
Frame Height [pixels]: 480
Bitrate Encoding: CBR
Bitrate [Mbps]: 8.0000 (high quality)
M Frames: 3
N Frames: 15

After authoring, I burned it on a Sony DRX 500-UL burner at 4x speed from DWS2. The DVD is stuttering some in playback in a few places on a couple different computers. Can anyone help me figure out possible causes for this and some fixes?

I want the export/compression to yield the highest possible quality but to have the maximum stability for playing in a variety of set-top DVD/tv players as well as computers. Thanks for any help.
