Eagerly tried 2.0 yesterday and found 2 problems.
1 as the title says watched a tv episode , trakt marked the progress all the way through but would not mark it as watched at the end , it stayed at 99% on the trakt website even after I had finnished playing the file.
2 Had one file that came up with the error. could not play audio . I had not experienced any file up to this point that infuse wouldnt play. I have an old version of 1.2 archived I will try to play the file on but unfortuunatly didnt archive 1.5.
