I'm using an MRSS feed file. I guess that explains the disabled category. Although, I'm not sure why a user cannot continue watching videos from an MRSS feed. Granted, they tend to be shorter, but, having the ability to pick up where you left off seems like a nice feature regardless of JSON vs. MRSS.
