I've recently started getting interested in building a home theatre based on a DLP projector. I've been looking at several different models and trying to learn as much as I can but can't seem to figure out what is really meant by HDTV support. At first I thought it had to do with the native resolution of the projector but I've found projectors with different resolutions that support HDTV. I thought that you needed 1080 lines to support HDTV yet there are 800x600 projectors that support HDTV. Can someone shed some light on exactly what is meant by HDTV support? It just doesn't seem to make much sense to me that an 800x600 projector can support it. Thanks
