how display multiple files as one movie?

[Iacov]

does it have to transcode?

.

I hope this helps. If you need anything else, just let me know.

thank you, that was way easier than expected. though I don't get the difference between add, append and the third option 

but my movies now seem to have the full length so I think I have done it correctly xD

funny thing is that I encountered an issue that apparently handbrake did cut away too many pixels on some of the files which prevents the merging. glad that I also keep the "raw" mkvs... so I multiplexed the file and than transcoded it again
