DIRECTV is now holding a free preview of nine High-Definition channels, including several movie networks.

Amazon: See today’s 1-Day-Only’ deals!

The preview, which began yesterday, will run until March 1.

The channels in the free preview make up the ‘DIRECTV HD Extra Pack,’ which normally costs $4.99 a month, although the satcaster will sometimes  offer them for free for three months if asked.

Amazon: Thousands of Blu-ray titles for under $10 each.

The Extra Pack channels are: HDNet Movies, Sony Movie Channel, Shorts HD, MGM, Hallmark Movie Channel, Crime & Investigation HD, Palladia HD, Smithsonian HD and Universal HD. (pictured: There Will Be Blood, which plays tonight on HDNet Movies.)

Amazon: Roku 50-inch Smart TV: $379.

DIRECTV’s occasional free previews — and three month free offers — would suggest the satcaster is having trouble getting subscribers to sign up for the special HD package. While the Extra Pack includes some interesting channels, there is not a standout to lure subscribers on a regular basis.
