thanks for the report! It might have more impact to send it to Codeberg,
I am not sure who still looks at Debbugs.

This is a very old project, dating from 2012.

So I wonder whether the best course of action would not be to simply
remove it; now since you sent in a bug report, I assume you still use it.
Are there no more modern programs doing a similar job? Handbrake can be
used to rip DVDs, but this transcodes. Just copy the files from the DVD?
I suppose that this leads to questions about how to decrypt the css.

Patch welcome...

Andreas
