I'm experiencing difficulty converting DVD's with a frame rate of 23.976 fps to DVD-R wihout some sort of synch problem. The typical scenario is the audio will fall further behind the video as the film progresses.

Firstly, I obtain the DVD data (i.e. aspect ratio, frame rate, etc.) from DVD2AVI.

Secondly, I let DVD2AVI create the .d2v and .wav files, using Forced Film and Dolby Digital Decode settings.

Thirdly, I load the 2 files into TMPGEnc and select DVD-NTSC (as there is no selection for NTSC Film), and increase the audio volume under settings. The 3:2 pull down is automatically selected by default and the only other adjustment I make is to select High Quality under Motion Search Precision. I make no changes to the Advanced tab unless I want to Clip Frame. I do not load the default TMPGEnc's settings for DVD-NTSC as I noticed this changes the read-out at the bottom from 23.976 to 29.97 (Perhaps this is my mistake).

Any assistance in resolving this dilemma would be greatly appreciated.

Yeah, problem is with framerate. Audio is always in certain length -- video is the one that framerate change effects to. So, if audio falls behind, it means that video goes too fast (==too high framerate, in your case 29.97) and vice versa.

Tweak with the fps and IVTC (3:2 pulldown) settings and you should be ok.

dRD,

Could you please be more specific re: the steps I need to take in order to produce a synchronized DVD-R.

I tried the 3:2 pulldown and no luck. I'm making a back-up of the DVD Mulan, which is animated. I understand animes are more troublesome.

If all else fails, I'll simply strip the unwanted material in Ifoedit and burn the VOB's to DVD-R.

For future reference, however, I just wanted to know if there was an established work-around for the synch discrepancy.
