desktube.tv lite is a program that will play YouTube videos without using a browser.
The program offers a lot of features to let you enjoy the video playing. It will offer you videos from a small amount of YouTube members, but you can also view videos related with any of the ones you have in your list. This way, the program will let you see a lot of videos, and the list will be different each time you use the program. Bad news are that you will not be able to search for a keyword and play the found videos.
Once you found a member that offers videos in which you are interested, you can "Subscribe" to that member, and the program will always offer you videos posted by that member. You will also be able to read the comments that other users left on those videos, or post your own comments. It is also possible to select just one video from any poster, and add it to your own playlist and/or your favorites. You will be able to play that video whenever you use desktube.
This program has versions that can be used on your Windows or Mac computer, tablet PCs or other mobile devices. In order to install in on Windows or Mac, you will need to have Adobe AIR installed.
