Biggest concern: we had to delete and restore our Hulu account because of a Roku issue and we were restored to someone else's account! Multiple efforts to correct were unsuccessful. Contacted Hulu phone support at 10 pm. Call was answered promptly, and their instructions resolved the issue quickly (leading us to suspect that this may be a relatively common occurrence?). That is a concerning breach of privacy. Other concerns: frequent 'failures to record'; generally non-intuitive user interface.
