Coinciding with the release of Heroes season one on HD DVD, NBC is offering the first episode on the Xbox Live Marketplace in HD or SD and for free. So, if you're an obsessed Heroes fanboy or a Heroes virgin like myself then feel free to dabble a bit in what the show has to offer and give it a watch. Even if you only download it for the sole reason of getting a chance to watch a TV show in HD. The free episode weighs in at 599MBs for the SD version and 2.4GBs for the HD flavor. Happy watching.
