How do I watch content on my DVR when I'm away from home? How often should I clean my projector's air filter? Why are optical-cable prices so wide ranging?

Q The foam surround on my Velodyne f-1200 subwoofer has disintegrated. I wanted to have it repaired with a rubber surround, but the guy at the speaker repair shop advised against that. Is there any benefit to using foam instead of a rubber surround when repairing a subwoofer driver? —Pete Gibson / via e-mail

I currently have a Sony KP-51HW40 51-inch CRT rear-projection HDTV. I find the picture quality stunning, with great contrast and solid blacks. Since it is a CRT-based display, I believe the black levels are better than most plasma sets. Is this correct? I ask because I'm thinking of upgrading to a 60-inch plasma, most likely the Panasonic TC-P60S30. I see from your review of the TC-P50S30 that it has what you call "reasonably good blacks" at 0.009fL. Is this black level much inferior (less black) compared with my Sony CRT? I am afraid of buying the Panasonic and having poorer blacks than what I am used to, because black level is very important to me. I am also curious about how the overall picture quality compares between both sets.

Restorative Power
When movies are restored for Blu-ray, why do some not look very good? Does it have to do with the film elements themselves? Why are some films harder to restore for Blu-ray? Are movies from the '50s, '60s, '70s, and '80s harder to restore in high-def than films of today?

More Power!
Years ago, I was told that there were several ways to rate the power output from an amplifier, but only one of those ratings was the "true" measure—RMS or continuous power. The Federal Trade Commission (FTC) got into the act back in the 1970s, requiring all amps over 5 or 10 watts to be rated in RMS watts with both channels driven. That requirement was lifted in the '80s, and now when I read power output specs, I don't know if they are RMS (root mean square), IHF (Institute of High Fidelity), or something else. Could you clarify this confusion?

Going Down
In the measurement section of some speaker reviews, I've often read that a speaker's -3dB point is at a particular frequency and the -6dB point is at another frequency. Could you please explain from what level the speaker is down 3 and 6dB?

I'm an avid listener of TWiT and have heard you on the Tech Guy and your podcast. Because of TWiT and the fact that I don't watch a lot of TV, I have decided to "cut the cord"—that is, dump cable and satellite. However, I would like to take advantage of digital over-the-air broadcasting. I remember hearing that you have a rooftop antenna with a motorized rotor for orientation adjustments. What options are available for different qualities and prices?

I'm planning to buy a 60- or 70-inch HDTV in a few months. The room where it will live is not totally darkened like a home theater. Besides watching TV and DVDs, we also want to hook it up to a PC. With this requirement, is LCD TV the way to go?

You have the best home-theater website, hands down. I also love your short guest appearance on Leo Laporte's radio show every week. I notice that you talk about plasma and LED LCD TVs a lot, but very rarely talk about DLP TVs. Even last weekend when you were the guest host on Leo's show, there was no mention of it. Is this because the technology and displays are not as good as plasmas and LCD TVs, or is it because there is no market for those TVs? Or is there another reason? I can get the Mitsubishi WD-92840 92-inch DLP TV for about $3300! No plasma or LED comes close to this price. If I want an 80-inch or larger flat panel, I'm looking at somewhere north of $10,000!

Defending RPTV
I think you're a little harsh on rear-projection HDTVs. They've changed. For instance, the 67-inch Samsung I bought last year has no lamp and no color wheel. It's lit by three LEDs that fire their color beams directly at the DLP chip. No lamp to replace, no mechanical troublemaker. Also, the picture fully retains its brightness within an arc that is realistic for most home viewing.

Finding RSS
I can't find any RSS links for the various blogs and posts! Am I missing them somewhere?

Can you recommend a TV for a small living room? The room is 18 feet wide, and current viewing distance on a standard-definition 35-inch TV is about 12 feet. I'm looking at the 42-inch size range for $1500 or less. I think I need an LCD TV with 120 or 240Hz refresh rate; I watch a lot of sports, and I'm not sure that 120Hz would be enough. Also, I think I want an Internet connection as well. I know from listening to you that this can update the TV, but can it access shows like what Leo Laporte and you do on

I want to buy a LCD TV with LED backlighting. I am not a "ultimate" kind of guy because I do not have the money. I am looking for a 55-incher for $3500 or less. I've heard you say Samsung is the one to get. What the model would that be? I think it is the UN55D8000.

We Don't Need No Stinkin' Boxes!
A satellite signal comes into your house and goes to the satellite receiver via coax, right? Why can't you connect the coax directly to an HDTV and get a high-def signal? Also, why do Dish and DirecTV advertise "full HD" when the signal is 1080i?

Is there a site that can help determine the right screen size for a given seating distance? In my case, the distance from my couch to the TV is 7 feet.
