Does anyone know of any programs that let you watch demos without opening ns? I have a not-so-fast computer and it takes a long time to load up ns and stuff.

This thread has been previously phased here:

There are programs which can start hl for you and directly open the demo you wanted with a few clicks, but it is not possible to view the demos in an external program.

how can you actually view demo without starting hl?

1. make an .avi - you won't need hl to watch it
2. use this: http://www.demofreak.com/ - it'll show in-depth info, including player-chat and more
