Did I post this this morning? Thought I did but can't find the post!
When I say missing data, I don't mean meta-data. Of my film rips (folders - VIDEO_TS and bdmv) a handful do not have data for duration, bitrate, and some others. I understand these are not user 'serviceable' fields, but are determined by the files themselves.
Some have wrong info - Fargo is apparently only 27 minutes long!
