Subtitles blury - pixelated

dvd2one works great for the most part. 2 movies - green berets and lawrence of arabia have probs with subtitles. the subtitles are there but the words are blocky and very difficult to read.
anyone seen this - or how to fix it??

Looks like the subtitles encoded in the stream?

If that’s the case the only thing you could try is to remove more content from that discs.

Encoded subtitles are the most difficult thing for every encoder/compress to reduce in size while keeping the sharpness
