Avoid the need to download all the rar files of a movie with RAR Movie Player. Download the first rar file and view the split movie file (avi, mpg, wmv...) to see if it is a) the right movie, b) the right quality, c) the right language d) ripped from the beginning.
No installer, just unrar to programs and drag and drop exe to Start/ All Programs to create shortcut. No system files created and no adware or spyware contained in rar. I have used this successfully for the last 2 months and it has saved me a lot of potentially wasted RS download quota.
To use simply click on File, Open RAR or Streaming From Unrar and browse to the required file. A Password box appears, either enter the password or (if no password) Delete or Backspace and hit Enter and a viewer will appear with the movie playing. This works on approx 90% of RAR s containing movies. I have personally used this for 2 months and it has saved me a lot of, potentially, wasted download quota on RS & MU. It is also a very useful video and DVD standalone player using the MPlayer engine.
