I think some users have a misconception of what Playon actually does. There have been people asking why playon doesn't use more threads to download videos. Playon does not download anything. It records what it sees. This is why it is legal as it is an iptv dvr that requires logins for pay content. yes this does make it slow. and yes I would love to see a multi queue but for some content this just might not work. not to mention more queues to record more content would require more CPU power and Playon is already fairly CPU hungry as it is.
As a lifetime subscriber, I can tell you that I believe it is well worth it and has paid for itself many times over.
