Software you need because it works  I tested the software with 50 concurrent downloads of YouTube videos each 50-minutes long without any problems. Version 5.4.6 is very stable.

MovieSherlock for Mac does what it promises almost flawlessly  Easy and intuitive: MovieSherlock for Mac lets you download HD and HQ YouTube videos with just a few clicks through its clean, accessible main window. Results are displayed with their respective thumbnails and duration information.

Well spent money  I was amazed at how easy it was to start watching a video and turn on Movie Sherlock so it would capture the video that I previously did not have any way of downloading or capturing. I have tried several other programs but none were as easy to use and had the capabilities that Movie Sherlock has. It was money well spent for results that met my video capture needs. When I did not understand something or the program did not work as I thought it should, I contacted their technical support and was very impressed with the level of suppert that I received. They went out of their way to resolve the issue and help me complete my project by offering work arounds until they were able to analyze why I was having problems with certain web sites
