A/V reciever theory question

I posted a few months ago for advise on what part of my system to upgrade first. Thanks to your help I've decided to upgrade my old Kenwood reciever. I am looking at the Yamaha 2500/2600, but a friend this weekend brought up a good point:

I currently have all video sources going directly to my TV (Samsung HLP616W), and audio to the reciever. The TV has nice video features built in. My question is, what is the benefit of routing audio and video through the reciever? Besides the obvious source switching or maybe 1 HDMI out from reciever to TV, if I have a good macro remote, why do I need it? Which brings me to my second question, could I then look at a lower priced reciever with all the audio bells and whistles and minimal video like a 5890? Its 140wX7 and THX, am I giving up any audio muscle?

please help me understand.
thanks

Actually, the 5890 features pretty much the same video features as most other receivers in it's price range. The denon 2805 is basically the same, just with less power (I think). I have never really seen the point of routing your video through a receiver, since it's just more cable to lose picture quality on. Seems like a laziness/preference/conveinience issue to me, and i personally have no problem with changing the video input channel on my tv for each component I have, especially since it saved me $100 on another componenet or hdmi cable that would run from my receiver to my tv.

Seems like i sort of side tracked there..... No you wouldn't be giving up any audio muscle, it's actually the opposite. Yamaha is pretty cost-friendly compared to some receivers out there, so it's not like ur paying too much extra money just for the yamaha name. And at $850, it's certainly no cheapo either (yeah, I know, there's $6,000 receivers out there, but I think $1500 is too much unless you're running five brand new klipschorns in there!). So if video goodies are minimal, the money is going into those solid 140W channels and other audio processing treats. Sounds like it would fit you perfectly.

Hello
Receivers and Pre-Amps video switching circuitry has evolved enough to be
Non-degrading. It is more a feature of convenience than anything else.
But you may benefit from video up conversion. In the past receivers and pre-amps didn’t have the bandwidth or quality in there video switching circuitry to be useful in high end home theaters

Thanks Hanse and RLA. That's a good point about video upconversion. So I'm getting the reasons to pass video through a reciever is:

Switching convenience
Video upconversion

Is there anything else?? If I could do without the above, could I theoretically look for any DD5.1_DTS 96/24_PL IIx with enough optical in, the watts/channel I want, and the audio features I want (lip sync delay, GUI menu, etc)? ooh thats another question, do you have to pass video through the reciever to enable lip sync delay?

In regards to passing video through the receiver to enable lip sync delay, the answer is no. It's strictly an audio thing. The receiver will ask you how many milliseconds to delay the sound output. And then you have to try out various numbers to figure out which one synchronizes to your TV the best.

cheers,
