After a few month of waiting , finally I got beta test invitation from Joost. I have downloaded it and test it. Nothing was working at first site, there was a connection error problem… In evening I received a mail from Joost side informing new 9.2 version and bug of 9.1 version. Finally, I had installed newer version and opened the program. The graphic is quite interesting and amazing just giving me feel a theater. Picture and audio quality of the program is very good. I found very fast good streaming ratio at 256Kbps internet connection speed. Joost supports many programs including National Geographic Channel and some Indian channel but not all of them are working now because of beta release.
The program is in beta and not open for public users now. You can register at site and it is up to Joost to send you invitation to test program. Joost TV also require Joost credential each time to run the program. The program can be run on multiple PC in same network or different network but you need to supply credential from each PC. This simply mean you need to expose your login id and password to others.
Now register on the site and wait for your turn to get the Joost work on your PC.
