MTS/M2TS video seems like missing frames after Firmware Update

hi all, i have two of this boxes, i’ve updated the fw to one to latest and left the other untouched.

now my videos mts/m2ts (recorded with a sony hd camcorder) doesnt play smoothly on the upgraded one .

after watching a while it cause a  headache

Does anyone has the same problem ?  is there a way to convert the videos to work as the original version of the hub ?

last version of firmware fixed the issue, finally some good news
