I just noticed it on the two episodes while watching, as it was particularly visible there. The clip is from 'Do-It-Yourself Mr Bean' (DVD2/Ep10), the other one is 'Back to School Mr Bean' (DVD3/Ep11).
I'm not sure, if there's dot crawl in other episodes. I may simply not have seen it, like it didn't faze Ghitulescu when watching the non-remastered version.
I also noticed some bad frames and tried to fix them in photoshop, could upload the results if you're interested. (Two frames from Ep3 'The Curse of Mr Bean' and 7 in the Special 'The Library')
Apart from that, I still don't know how to get rid of the dot crawl at least to a point, where you don't notice it when watching. (In order to push this discussion btt
