I've most recently been having trouble tagging certain .mp4 files. Most work but in converting some of my DVD TV seasons to digital I've noticed that some do not tag right. I encoded the .mp4 files with Handbrake and used pretty standard settings; most of the files tag correctly but it seems like the last item per disc has trouble retaining tags. However, when I edit the fields in Windows Explorer the fields seem to stick just fine. Here's one of the problem TV Seasons and as you can see with the highlighted files I added some of the fields through Windows Explorer fine but if I were to try to edit any of the filled in fields like the bottom file, it clears out the field I tried to edit. Any thoughts on what could be happening? I'm using v2.58 and I never had this problem with v2.57. Thanks in advance!
