We understand, you're not ready to let go of the BSG season finale just yet even though Tiger and Phil are charging up the back nine at Augusta, but keeping a lot of HD on the DVR can fill up space quickly -- which is where these two come in. Amazon is now taking pre-orders of the long-awaited 1TB edition of Western Digital's TiVo compatible (or other eSATA enabled box) DVR Expander, although no ship date is listed, and Apricorn took our advice on its fugly 500GB, 1TB or 1.5TB sized boxes, giving them a sleek new look. It's dual USB 2.0 / eSATA compatible, but not TiVo, so Scientific Atlanta 8300, DirecTV and DISH ViP owners can claim this one at $219 for the 1.5TB, while the WD will set you back $183.

Want a taste of the SlingLoaded DISH Network 922 DVR (pictured), without switching to satellite? Echostar, as expected, is ready to show off a tru2way compatible version of its latest box, the T2200S, this week at the Cable Show '09. The T2200S contains the 1TB hard drive, expandable storage and of course, Sling Media's placeshifting technology ready to send live or recorded TV to your Internet connected device of choice. Since it's tru2way, it's also capable of running either the SlingGuide software, or whatever middleware is chosen by the provider, and enabling remote video diagnostics, hopefully making many truck rolls unnecessary. Like the 922, we've no price or release date yet but hopefully all that work on tru2way and M-CARD means whether or not our cable company signs up, we'll still have the choice of purchasing one at retail.

Update: Looks like the box is planned to start testing June, and go into production in Q4 of 2009, the specs from the PR are after the break. [Thanks, Justin]

Sharp's back again with four more Blu-ray DVRs unlikely to ever see release here in the U.S., but all the rage in Japan. The main upgrade from last year is improved compression, going up to 7x, squeezing HD down to 3.4Mbps MPEG-4 AVC to fit up to 30 hours of HD on each disc. The top of the line BD-HDW40 features 1TB of hardware storage, dual digital TV tuners, 1080p/60 output, BD-Live, and all the oxygen-free copper cabling and anti-vibration tech one would expect, with the other three spec sheets causing predictably lowered paroxysms of pleasure for slightly lower prices.

Love it or hate it, the HR20 is here to stay, and one thing its got going for it is a 300GB hard drive, which is bigger than just about any DVR sold today -- including the Series3. But, just like many other DVRs out there, it is possible to upgrade the drive to expand its capacity and WeaKnees is there for the faint of heart. WeaKnees is well known for their TiVo upgrades, but now they are adding the HR20 to list. So for $999, you can now get an HR20 with 1TB of storage, which should go a long way in the world of MPEG4 or HD-Lite.

It's one thing when the most taxing task your DVR will ever face is the furious fast-forwarding necessary to get the next scene in your favorite recorded drama, but if you've got over 100 hours of HD VOD to churn through while recording tonight's game and sifting through next week's programming list, having a more intelligent hard drive just might help out. In an effort to reduce DVR hard drive fragmentation, lengthen the life of set-top boxes, improve the quality of service / speed to the end user, and give your average DVR the ability to "manage up to 14 HDTV (19.3Mbps) streams from a single 3.5-inch HDD," Hitachi has developed AVSM technology to help your DVR's HDD think things through before going through the motions. The background software differentiates between "streaming applications and best-effort, non-real-time applications" such as electronic program guides, IPTV downloads, and photo browsing in order to manage the line of tasks more efficiently. Overall, the software reportedly reduces duty cycles "by up to 60 percent" and all but eliminates disc fragmentation, but realistically, with new units popping up entirely more frequently than your average hard drive takes to perish, hooking DVRs up with all these smarts might be a bit unnecessary for those who stay on the bleeding edge.

We've seen HD DVD-R and HD DVD-RW media announced repeatedly over the last few weeks, now we can see the -- huge -- box you can put it in. While standalone recorders aren't the biggest market here in the US, we've heard they are very much in demand in Japan and this should definitely satisfy. The RD-A1 will debut in Japan on July 14, for a cool 398,000 yen ($3466 US). Reuters reminds us that Sony has had Blu-ray recorders available in Japan since 2003, although at a starting price of 450,000 yen ($3916 US).

Interestingly, this device will output 1080p via HDMI, unlike Toshiba's HD-A1 and HD-XA1 HD DVD players. The RD-A1 also uses Toshiba's existing "RD Engine" hard disk drive recording system to record content from 1 analog and 1 digital tuner (simultaneous recording is supported) to the 1TB hard drive, edit to your liking, then burn to either a 15GB single-layer or 30GB dual-layer HD DVD-R (no -RW) disc. Interestingly, it does not support recording in newer codecs like VC-1 or MPEG-4, only MPEG-2. As early Blu-ray releases suggest, even a dual layer HD DVD may not have the space to provide ideal video quality, although there will be no PCM soundtrack to take up additional space. You can also stream content to DLNA equipped devices like Toshiba's Qosmio laptop. An undocumented feature is the ability to drop it on any small children or Wicked Witches of the East you want to get rid of , because the thing is enormous. No word on US availability yet.
