When the Sundance Film Festival guide was first distributed just after Christmas, it said one of the Park City venue houses would be the "Microsoft HD-DVD House," where you can come and see the latest high definition disc technology known as HD-DVD.

One problem though. Warner Bros. announced afterwards that it would support the rival format Blu-ray exclusively and drop its support of HD-DVD. That gave a huge boost to Blu-ray and may effectively end the high-definition disc format war since a vast majority of studios support Blu-ray.

Shortly after Warner's announcement, the Microsoft HD-DVD House was re-dubbed the "Microsoft House," according to a source in Sundance.

Losing a format war certainly can suck the air out of you in a hurry.

But fear not you HD-DVD fans, a Microsoft spokesman said that nothing has changed at the house, that "HD-DVD remains a focus of the house and a presence at the festival."

In fact, Microsoft, which exclusively supports HD-DVD, is holding a press conference Sunday at 7 p.m. to announced new things for the failing format.
