Great info, thanks. That's a 4-6x size improvement from what I'm seeing now, so that'd be very helpful. Probably actually cheaper to buy this than just get a larger HDD.

I'd looked at options that would auto-transcode recordings on disk, but they generally changed enough things that it wouldn't maintain the metadata and/or otherwise treated them as individual videos and not episodic content.

One last question, do you happen to have any extenders? I'm using an xbox 360 as an extender and I wonder if it can play the h.264 encoded video.
