Hello, hope somebody can help me:

- I have 90 videos in HD 23,976fps
- I have another 90 videos in DVDRip with 4 differents audio languages in 25fps

So I wanna add those audio streams of the dvdrip to the HD version videos, but I can't figure how do it as batch bat file..

I tried with FFmpeg and MKVmerge without success.

thanks for any advise
