While this week has had its share of bad news from some corners, it turns out that the last few weeks have been a really wonderful time for many HD DVD owners looking to build their libraries.

It had been reported in a few places that Planet Earth was out of print, which led some people to entertain discussions about Warner (who distributes the title for the BBC here) and format support. Checking this morning, it’s back in stock at Amazon for $55, right through Amazon itself and not one of their associated vendors.

Here’s a look at some of the deals that are currently available. Many of these are continuations from earlier in the week. The anti people will say some of these are fire sales. In truth, Amazon’s “Buy 2 Get a Third” sale, for example, is happening on both high-def formats, with a few more titles on Blu.

Without further ado, here’s what you can look forward to over this weekend:

• 50% off HD DVD at Barnes & Noble, even more off with membership.

A little birdie tells me that using code Y4R4K7D might save an additional 25% on a single item

• 50% off sale at Amazon.com

Don’t forget to also see if something interests you in the buy-2-get-1 free offer

• Amazon Buy 2 Get the Third Free

This one can get confusing because of the 50% off sale that’s also going on. Your cart might become a confusing mess of discounts, consider placing separate orders.

• Buy One Get One Free at Best Buy from Feb 10 to Feb 16

The trick appears to be to have them ring up the cheaper movie first

• Movies under $16 (some are $11 and many are $12.20) at DeepDiscount.com
• Tower has 52% off too, but the movies are not listed in any friendly order
