Thanks for the further information.

Can you take a smartphone photo of the last watched list and the video folders list (with padding turned on and turned off)? I'd like to see the difference. Email the photos to us at support [at] conceiva [dot] com. We may be able to improve it.

The MPEG-2 format can be problematic with Samsung TVs since we've found that FF/REW/Time Search is disabled for MPEG-2 files in the TV's firmware. I'll send you a device profile with MPEG-2 encoding turned on for default transcoding and you can confirm this for us for the newer Samsung F-series TVs.
