Need tutorial for subtitle problem

I just downloaded a film that is in 2 files, part 1 and 2, I need a tutorial on how to add the subtitles. I only have experience putting subtitles on films that are all in one file. I’m using AV1Recomp and ConvertxtoDVD. Any help appreciated.

If the videos are encoded in the same manner you should be able to join them into one file. You can do this with AviDemux.

Great, thanks for the tip.
