Have you noticed a drastic drop in quality in PLAYBACK vs LIVE? Since these firmwares updates, all my V2s and Pans have a big reduction in bitrates when using PLAYBACK. My V3s don’t have this problem, bitrates are the same when viewing in Live or playback. 4.10.8.860 and 4.9.8.860
One of my V2: Check the bitrates droppings in Playback mode vs Live viewing.
One of my PansV1:
One of my V3s: No dropping in playback mode. It is the same quality(bitrates) between Live viewing and Playback.
EDIT 
: Checked some playbacks before this update and the issue is there also. 4.9.8.829 and 4.10.8.829.
