Hi there I am converting VHS tapes to DVD, usually 10-12 individual clips per dvd. And am converting them to MKV files, hoping to merge them together so the clips run seamlessly (some of the clips end on vob1 and then continue on vob2 etc) and I want to then edit them correctly in PowerDirector 9.
After the process has completed and I load the files into PowerDirector, they are missing the audio track.

I have searched for an answer and wondered if someone could help me out. I'm not very techy and really don't know what to do. I have about 100 hrs of tapes to go through and this is causing a headache.

Thanks in advance.

Post mediainfo output from the files

I have no idea what you mean or how to do that.

Its likely just a issue with powerdirector...

If you have the vobs you can just cat them together (cat file1.vob+file2.vob+filen.vob merged_file.vob) and skip makemkv and powerdirector.
Alternatively you can use x264 to compress them.

edit (on windows: copy /B file1.vob+file2.vob+filen.vob merged_file.vob)
