2 days ago I decided to upgrade this add-on. I was tired of not being able to download the better quality vids so I can view them when I have time. I had a problem completing the transaction so I left Dishita a message. I couldn't believe it when I received an e-mail from him the next day (on Christmas eve) explaining how to easily solve the problem. I'm now able to download the best quality vids & it's super quick. I only have a 12 MBs connection but it's still extremly quick. Seconds instead of sometimes 20 minutes in the past. If you're not using the pro version you're missing out big time.
