Nero Vision Express 2 - How do I avoid lengthy transcoding?

Hi,

I’ve just started using Nero Vision Express 2 for authoring DVDs from captured video.

Can anyone please enlighten me on how I go about finding out what the MPEG2 data rate etc. is in the captured files and how I can set up Vision Express to match so I can avoid 15 hours of transcoding for a 2 hour video file ?

Are there any utilities available that will show the MPEG2 details for a given video file ?

Any help would be much appreciated as I’m becoming very frustrated with the incompatibility of supposedly compatible MPEG2 file formats !
