Greg, I must say that I'm a software developer, and not a hardware developer, so I can't say with total certainty how a PVR-500 actually works.
That said, the set-top box that I was working on has the same idea as the PVR-500: two tuner chips (the same chip for both paths), with one coaxial input. Therefore, it is a "splitter". However, I don't think that it's the same as a regular splitter - I don't think that you lose 3.5dB, like you would with a regular two-way splitter. (I'd have to look at the schematic and talk with the hardware engineer to be certain). Plus, if there was such a high loss, then the engineers should have compensated for it by driving up the amp a bit (which is generally done in the software, and not in the hardware). I'm sure that the LG tuner part is probably cheaper in quality than previous parts, but I have a hard time believing it's that crappy. I'd believe a bad run more than that. BTW, by hand crimping, I suspect that he means the coaxial connectors that have to be put on and tightened with a special tool, and are very tight (i.e. you have to strip down to the copper wire before putting them on), versus cheaper connectors that stay in place via soldering or screw-on methods). There's definitely a difference between the difference connector types, we've seen that at the office in the past (running coax between a CMTS and our cubicles, for instance). -- Joe --- Greg Woods <[EMAIL PROTECTED]> wrote: > On Mon, 2005-09-12 at 19:28 -0700, Joe Votour wrote: > > I've read the thread you you mention, and call me > > skeptical, but I don't buy it 100%. > > Neither did I.
