"Open source" Version 3.4.4 includes adware.
Useful, but limited to 25 downloads so hardly freeware (trying to download a large playlist of lectures for offline viewing; 25 doesn't cut it). Official website claims product is completely open and free and unrestricted, which is obviously bollocks. So who knows what else about it is bollocks. Don't have time/inclination to go through the sources myself at the moment so will use something else. Also, downloaded the zip, and the first thing it wanted to do is download a binary exe installer for a "bug fix" - so they aren't inclined to keep the sourceforge version up-to-date, wonder why.
I downloaded the application to my imac and it works with no trouble at all but I have just downloaded the latest version to my book air and it crashes on opening. I deleted and downloaded half a dozen times but no good. Please advise someone?
Works well in linux
