first of all: I really like the “previously viewed video” option on the video page. unfortunately it's a bit buggy. there are videos which I haven't even clicked on, yet they have the green checkmark as if I have already watched them. and then there are videos which I already have downloaded to my harddrive and the main video page still doesn't show them as viewed (I have to reopen the page of the specific video .. then the system tracks it correctly). I think it mostly happens when I download a whole series (part 1-4 for example) and open all 4 parts in multiple tabs (all within 2-3 seconds).

oh..and can you add a filter option “don't show already viewed videos” or something like that on the video page? now that the video library gets bigger and bigger, it helps to only get the unseen videos in the search results..
