Comment (by Tjoppen):

 Alright, I managed to figure out what nonsense to enable for Google Drive
 to work. ffprobe -show_packets 0036fbv01.cf5cc84a_53374fee.mxf says that
 all packets are 240000 bytes except for the last one which is 247936.

 I dug into the file a bit and it looks clip wrapped, but the essence
 container KLV is not a multiple of 240000 bytes. This causes the size of
 the last packet to come out wrong. The reason for this seems to be that
 the body partition has KAGSize=131072, and Panasonic's MXF muxer being
 broken. The correct thing to do would be to insert KLV fill instead of
 padding the essence with NUL bytes. The fix is basically to patch the file
 so that the padding is KLV fill instead of garbage essence.

 TL;DR: Not a regression, the file is broken. DV is CBR, the essence in
 this file is not, due to incorrect padding.
