Tmpgenc dvd mpeg is not smart rendered by Nero

[perfection]

What could be the reason that the DVD compliant mpeg file outputted by Tmpgenc Xpress is not smart rendered by Nero into a menu authored DVD??

All variables appear to match so why this rejection by nero??

What are the characteristics that cause a program to be smart rendered as against re-encoded by an authoring application??

Well you aren't going to get much help or sympathy on these forums for Nero use. In my own experience mpegs or VOBs personally encoded with HCenc, Quenc, Mainconcept and ConvertX have not been re-encoded. I have no experience with Tmpgenc. I recently ripped 3 Shadow Dancers DVDs and combined parts into a promo vid using Nero Vision to insert various, periodic text announcements and transitions. I was glad to see that only the parts with text and transitions was re-encoded (SmartEncoding was listed at 91.8%). I use Nero 7.

You might also try, as a test, setting your project as DVD-9 just to make sure Nero's own overhead isn't the culprit.

You might try MediaInfo, closely comparing ones that work against those that don't.

MysticE speaks much sooth. Nero is so badly written that the wonder isn't why it sometimes fails, it's why it ever works. Of course, this doesn't mean that Nero is at fault in this particular case -- your source may be off-spec in some way. But problems with Nero are so plentiful that it's hard to know where to start looking. If you're really determined, you can spend a lot of time comparing different collections of assets to see which ones provoke the error, and which ones don't. Or, you can do what most others advocate here, which is to ditch Nero and use something (almost anything) else.

TMPGenc is notorious for ignoring your maximum bit rate value and exceeding it by up to 1000 Kbps. So, for example, if you set the maximum bit rate for, say, 9300 Kbps, TMPGenc might actually have gone over 10000 Kbps for brief parts of the video. You might be exceeding the maximum bit rate allowed fro DVD, hence Nero's unhappiness (Nero checks the max. bit rate in your video and will reject it if it's too high). Of course this may not be your problem at all, but I just wanted to suggest it as a possibility. Because of TMPGenc's issues in exceeding max. bit rate, I suggest that you not use a value higher than 8100 Kbps when encoding with TMPGenc to give yourself enough room if it exceeds that value by a lot.
