I've decided that the best way of auditioning the various Hi-Def TVs that I'm considering is to take my TabletPC with me to the shops and feed a Hi-Def video into each TV. So, my question - any suggestions on the best 720p hi-def video file out there to use for the test. Anything that VLC-0.8.1 can play, and it has to be 720p. I'm looking for something that will put a HDTV through it's paces, test the full colour range, subtle shades, flesh tones, etc. I'm primarily looking at testing DLP-RPTVs. Thanks.
