I purchased the Memorex MVCB1000 from Rite Aid drug store about a week ago. The price was $69.99 ($29.99 plus full price sales tax after the $40.00 government discount). In this week's Rite Aid sales flyer (7/11 -7/17, Los Angeles, CA), the Memorex is priced at $59.99, and the store refunded $10.00 plus tax back to me, when I went in with the flyer and my receipt. Anyone interested in this box should be aware of the lower price. It may be the new price, but it also may only be on sale this week or for a limited time. I'm not sure if the Memorex is being sold by other retailers.
The box is said to be a clone of the Tivax converter. While I haven't seen the Tivax picture, which was well-rated by Consumer Reports, I am very pleased with the Memorex picture quality. It scanned channels, easily. I have more channels, now, but I also can't get a major channel (ABC). I guess I need a better antenna. There is analog pass-through, as previously mentioned.
The Memorex box does NOT function like the Tivax, when the power is shut off and turned back on. Starting in "standby", it goes to "standby", when the power is turned back on.
The remote fits well in your hand, but it functions somewhat sluggishly. It's not as responsive as I would like. You have to really press the buttons, and it has to be pointed directly at the box or commands aren't received. It runs on two AA batteries.
As mentioned, previously, there is no RS232 or smart antenna interface.
The box, itself, is black, and the casing is, primarily, metal with a plastic front. It is well-ventilated (top and sides), and it doesn't seem too hot to the touch during operation. It automatically shuts off after four hours of operation. That may be a setting that can changed. I'll have to read the manual.
All in all, I think it's a good box. Of course, being without timer control is a major flaw. I see myself purchasing a High Definition TV or DVD recorder with digital tuner in the near future. Somehow, I think that was exactly the government's plan, when they devised the whole converter box program.
