I use TMPGenc to create DVD and Blu-ray streams. Will these pass through DVD architect without rerendering? I currently use DVDitPRO HD which does allow these streams to pass through but all support for that product has been dropped.

As long as all the video streams / files are DVD or BD specification compliant and the audio files are AC3 DVD Architect shouldn't have to touch them in a rendering sense. It will just build DVD discs into AUDIO_TS and VIDEO_TS folders ready for burning to disc. With BD discs it just creates an ISO image ready for burning.

I seem to remember using TPMGEnc some time back for some obscure reason to create a DVD Program Stream and it created an MPEG-2 file that encompassed an MPEG Audio Layer 2 audio file. DVDA will quite quickly render that to an AC3 compliant audio stream if that is the only part that isn't compliant. Usually one would render separate video and audio streams to bring into DVDA for compiling when you author a disc.
