Megui audio passthrough?

[eastfamily]

I convert MPG TV shows to MKV. Is there a way that I can set the video to be converted and allow stream copy of the audio stream instead of converting it?

If the file is already 448kbps AC3 5.1, why do I want to re-encode it to 448Kbps? Can't I set it up to mux the two pieces together after the video conversion is done? Or do I have to use multiple steps?

If you only add the video file into MeGui, then it will only produce a .264 file. Then you could mux the .264 with the .ac3 with tsMuxer and not reencode the audio.
Or, you do the same with the video file, and after it has finished, you could use MeGui MKV muxer. Personally, tsMuxeR is my choice. :)

The propper method for MeGUI is to index it first ... with the indexing tool (DGIndex) you can demux the audio ...

Then with MeGUI, setup the video input / output and click "Auto Encode" ... it will bring up a window with initial muxing paramters (tick "add extras" down the bottom) and select the AC3 stream that DGIndex demuxed ...

Result will be an MKV with the AC3 track muxed in with propper MPG TS indexing (risk out of sync audio without indexing) ...

Thanks for the tip 7ekno. Damn, they make it difficult enough!

If I recall correctly, using the one click mode you can have the process 7ekno mentioned in one go without manual interaction.
