Top Gear has a web site that posts every episode for download. The latest season was posted in SD and HD. The HD was .mkv file so it required mkv2vob converter to format as mpeg2 for streaming from PC to PS3.
IT LOOKED AND SOUNDED GREAT IN HD!
Dr. Who has the same set up. Bummed I did not bookmark the Doctor's site. HD Doctor with Dolby Digital! Same as above, it looked fantastic.
