I purchased a Proxima DPP6850 off ebay. Because the projector is a few years old, it doesn't have any component video capability. It has composite, s-video and two rgbvh (VGA) inputs.

The Internet Control Message Protocol (ICMP) has many messages that are identified by a "type" field. I use the types to specify what actions to take in my custom iptables config.

Digital AV Out

To watch Gamecube games in progressive scan, you need to have a gamecube with digital out. Since 2004, Nintendo took the digital port off the gamecube. You can get your gamecube replaced with a model with the port directly from Nintendo.
