Nice tracks - i really liked it - but my Hometrainer went a bit nervous on the gpx data probably you should try to reupload and let the gpx data go through a correction through free gpstrackeditor - this helps me a lot with my own videos (there is some correction tool) sometimes the download fails then you have to search for alternate download - or you just upload to strava (private) and redownload. - Hope this helps :)
