There aren't any settings in DOL2 regarding the video player but thankfully, Dreamlink is really good at keeping their STBs up to date and squashing bugs via OTA updates which come pretty much monthly at this point so expect this to be fixed soon. In the meantime, the only option I can think of changing in DOL2 is HLS Start Mode (from Fast to Normal).

Is it all VOD or just 1-2 titles? If its 1-2 titles then it could be bad encoding on the file.
