Adobe Encore FORCES transcode

[juantohu]

Hello mates,

After encoding with CCE+AviSynth I'm using DGPulldown to flag up the MPEG from 23.976 or 25 to 29.97, but when importing to Adobe Encore a transcode is forced... is someone familiar with this problem?
Does this has something to do with the way DGPulldown applies pulldown flags? If so, should I apply pulldown before encoding with CCE? maybe an AviSynth script or something... or which program is similar to DGPulldown (altering MPEG2 RFF/TFF flags + no need to process audio)?

I'm pretty sure my files are 100% DVD compliant (I can author with DVD-lab and everything is fine)
I thought that maybe it had something to do with Open/Closed GOPs, but I did a test and it doesn't make a difference, except for a warning in DVD-lab, but the DVD is still playable.

Thanks.
