Many receivers do not do any video processing, they just pass through and switch. The only processing an A/V receiver will normally is conversion between sources. So if your TV is native 720p you want to output only 720p signal. If you hook up a DVD player that only does 480p, then the receiver would have to convert that. But many consumer all-in-one receivers (and TVs) do a poor job of that so it up/down conversion is a priority, you might want to look at using a separate encoder/decoder box like a Faroudja.
If he isn't using a receiver, how is he hooking up his speakers? Even if it does zero video processing, having an A/V receiver is worth it for other reasons - like having to run only one set of cables to the TV. And normally A/V receivers are more flexible terms of what ports and sources you can hook up as opposed to a TV. --- Brian On Sat, Aug 23, 2008 at 1:25 PM, DHSinclair <[EMAIL PROTECTED]> wrote: > My older Brother is now deep into a search for the "perfect" upgrade from > his current analog TV to a (ATM) 42in hdtv. > He called last night and says he will not need to buy an AV receiver > because his sales folk say that the AV reciever does zero video processing > of an incoming singnal-it really only deals with audio.
