Hello

I am using the trial of DVR-Studio Pro, and when I use the DVD Wizard to create the VOB files from .rec files created by the Topfield 5800 I can only seem to create a dvd with MPEG1 audio (no AC3).

However, if I use something like VideoReDo to read the .rec files and re-mux them via the save option, and then pass the files to NeroVision Express to author the dvd (which takes an age due to the re-authoring), the resultant dvd does have AC3 audio.

As someone who is fairly new to this, what do I need to do in order to get an AC3 audio track with DVR-Studio?

Normally DVR-Studio handles AC3 without problems. The audio-tracks are listed in the info-area in the topleft corner of the software. Often there is a MPEG and an AC3 track. You can also see them on the 2nd page of the DVD-wizard (when not using Express DVD function).

Maybe the mpeg track was listed first and so you would have to switch the track manually on your DVD player or you reorder them in the DVD-wizard. There also is an option "list AC3 audio first".

That's the confusing thing though - there is no ac3 track listed at all, just an mpg track at 356k, and another mpg track at 64k. When I have created the dvd, I just get an mpeg-1 audio track.

That's really strange. Try this: change the file extension of the file to TS, i.e movie.TS - make sure file extensions are visible in Windows file explorer. Then try to open the TS file with DVR-Studio.
Topfield REC files have a special header and DVR-Studio reads the available tracks from there. If for some reason this header is wrong (maybe because the AC3 track was added later in the recording) DVR-Studio will be misguided. By renaming to TS DVR-Studio searches for audio tracks itself.

No luck - it displays one audio track (mpg at 256k), if I look at the resultant vob file with gspot, it says that the audio track is MPEG-1 layer2.

But if I create the vob files with Nero, I finish up with AC3 .......

Now I thought that the audio from the Topfield does not contain AC3 (our DVB in the UK does not produce AC3), so maybe a Nero plugin is creating the AC3 audio from the mpg audio? Is there a similar plugin for DVR-Studio?

Maybe Nero does this, it's possible. We cannot do this - AC3 encoding requires very expenive licences we cannot afford.

OK - thanks for trying to help anyway.
