With the free version, I could d/l any quality mp4 but no mp3 at all. The reason stated was that HQ 1080 required too much server - I was trying to d/l only 128! All in order to get me to pay to upgrade to PRO. So I did.

All d/ls now are effortless and fairly quick. A 1.5 hr interview was converted in less than 4 minutes. And it doesn't break or stall in the middle like other d/l-ers do.

Definitely worth the donation! Keep up the good work!
