What is this s***?

I thank jonelondon for the review.

piece of s*** bloatware that redirects you to porn websites

Doesn't work at all. Seems this project is no longer maintained.. I would still use houlo video downloader.

Couldn't download current youtube content "Silent Epidemic: The untold story of vaccines". Video ID: K1m3TjokVU4. I would have a look at 4K Video Download Helper or xVideoServiceThief instead.

Thanks for software and updates.

Easy for use.

What the hell? Just download zip file, extracted it and ran the file. It automatically open Internet Explorer and loaded this crappy malware called Avasoft Antivirus. Here's how it looks like: deletemalware.blogspot.com/2013/03/remove-avasoft-professional-antivirus.html Seriously mate, what's going on? Just a coincidence? I don't think so....

Don't know if its a false positive or not but my box detected a trojan

Cool project, thanks for showing!

A must have, Very useful tool. Thanks!

I can not believe it. This is a great program. Apparently those that had a problem did not read the screen. I was so very pleased to have found such an easy complete program.

It doesn't work, all it does is install a "duplicate file finder", nothing whatsoever to do with downloading youtube files.

It doesn't work on mine at all... no error popups... and I have no idea how to even navigate. Make it more usable and also allow it to provide informative yet simple status of the downloads.

Caution!!!!! Spamware

why do you not provide the sourcecode without request - you selected an OPEN SOURCE license, so respect it!! (thats why) I created my own projekt - look here! https://sourceforge.net/projects/ytd2/

I use it many times with good results. The problem with FLV on Mac: get FLV crunch (a converter) and it's solved. Good Luck, Evert
