I'm using Mac the Ripper to rip individual episodes of TV series (yes, I own the DVDs) and then Popcorn to convert them for travel viewing on my PowerBook. The issue: I'll rip, say, six episodes and then drop the VOB file into Popcorn. Popcorn will convert five of them but one will show up as having no running time and will not convert. I don't want to rip one long file with six (or more) episodes. Is there a reason why Popcorn won't recognize one out of six episodes? It's happened with two different TV series. Thank you.
