Edited because I just noticed you do know what to to with two separate files (which I should really have guessed).

There are two different Guardian playlists on youtube: one is all softsubs and one has the Orange Biscuit ones as hardsubs. I guess you have your videos from that one. You'll find that from 6 onwards you'll get mostly softsubs.

I'll make an upload of the unsubbed 1-5,23,28,34 bundle and link it for you.
