Pretty good summary, Barry.
I would just add one thing -- analog doesn't have to be grainy, noisy or ghosty. If it is, we may have a plant problem to your house that needs to be addressed. Admittedly, an NTSC signal is not going to look like a 1080i signal, even when run through the best upscaler, but it should still look decent.
But if you're seeing problems with your analog service from BHN, give us a call and have a tech come out and check it. It's amazing what one little nick in the cable, a loose fitting, or a bit of corrosion will do to an analog signal.
HD-DVR -- two tuner, with most of the same functionality of the SD- DVR.
I've started my own HD-DVR list, so if you want one, PM me with your name and account information and we'll have somebody call you to schedule an install when they're available. No info on pricing, but if you're interest in box capabilities, it will be the S/A 8000HD with a 160gb hard drive.
Fox Sports Net -- I'm not involved in the SD programming decisions, so it would be speculation at best.
