I was wary at first, as I am of all 'downloading' software, but after carefully trying out EYVDE, I found it to be robust and reliable. It worked well enough that I subscribed to the Pro addition and found the extra D/L quality worth the price, and also the support provided to be quite above average. Even when there was a problem a month or two ago due to YT futzing around, EYVDE's developer worked it out and the add-on is back to working as usual. I nomally don't take the time to write add-on reviews, but this one deserves a 5-star rating. I have found that the add-on (and its support) is just that good.

There is a big problem with update screen. If I run a unattented screenrecorder and after 2 hours your update screen come into foreground my recording is garbage.

I paid for the Pro activation, and it is well worth it. I recommend it very highly. I have been using it for a few years now. It's easy to use. The developer quite often updates it. It updates automatically. I haven't had any problems with it.
(One nice thing is you can avoid a lot of advertisements, by downloading.)
It's good for mp3 downloading as well.

I clicked on the extension. It said to post the extension to a YouTube something or other. I had no idea what that meant.
I have never been able to use it.

This addon has allowed me to greatly increase my music library and expand my listening enjoyment. Dishita is always on top of code changes. The addon is very reliable.

Very simple and dependable add-on. Excellent support from the author.

Feio que dói.
Mas funciona bem.

I have been using his down loader for years. This is just what I wanted and needed to get the music I actually want to listen to, for personal use.

This is by far the best YouTube video downloader I've found. Depending on the size of the video, this extension is fast, easy-to-use and dependable. If something's wrong, Dishita is gracious enough to check things out and provide a solution. Recommend it highly.

Update: A few days ago I got this error message: "This application has expired. Please contact support."

I contacted the Author of this app, and he responded the next morning with the Solution. Updating to the latest version corrected the error, and again, it works perfectly.

Edit Oct-24-04 Dishta has worked very hard in adapting this Add-on to YouTube's ever-changing policies. With his help, I have successfully activated my Pro Account, and it works very well. Very much worth the small investment.

I have tried quite a few different extensions for downloading .mp3s from YouTube, but Easy Youtube Video Downloader Express by Dishita is by far and away the most reliable app available. The developer is quick to respond to changes in YouTube's code, and has excellent communication with questions, Recommended!
