Do I connect video out thru receiver or to TV?


I just got a denon AV and set up a Home theater to my TV. I have my psx2,dvd, and direct tv hooked to it. I see all the video inputs in the rear and wonder if it makes for a better connection or have any advantage to run the RCA, s.video connectors through the receiver or should I run directly to the tv? I have often wondered why the video connections should be through a sound receiver but didn't want to ask a dumb question. I'm asking now. Also what is the best connection to make, an optical, coax or RCA. Thank you for any help, Chas

Hi. Don't worry it's not a dumb question at all, actually you can do it either way.

The easier, less costly method would be to hook all your AV cables into the Denon and run only one video cable from your Denon to the TV. If all your components have S-video outs and your Denon video switches internally in S-video than you might not lose any noticeable video quality. You'll save on video cables this way too. My pre/pro will only switch in all RCA or all S-video, but not a mix of them, so everything I own has S-video outs that run into my pre/pro, and I run a single S-video cable to my TV.

However, there are many people that are more disciminating about video quality and will run individual video cables - S-video or component - from their sources directly to the monitor. If you have expensive equipment or can see a difference and have the budget by all means do it. If you only have one video cable on hand, try hooking up a component like your PSX2, DirecTV or DVD directly to the TV, and then through the Denon and see if you discern any difference in quality. Hopefully you won't and will be able to get by with only the one cable.

Good luck and let us know how it goes!. And remember, there are no dumb questions here, only an occasional goofy answer.
Ooops, I didn't address your last question regarding optical, coax and RCA. I'm assuming you're talking about audio only here. The optical and coax inputs are for audio and video sources that themselves have digital outputs, such as your DVD player and DirecTV receiver. Does the PSX2 have one also?

The optical and coax inputs on your Denon mean that it has an internal digital to analogue converter that will take the digital audio signal from your source and convert it for Dolby Digital or DTS playback. There are many people who favor using the optical [Toslink], but I happen to be one of those that like to use the coax with RCA termination. With either of these methods you only need to run one audio cable from your source to the Denon. The other method, and I don't favor this, is to utilize the internal D/A converter in the source and run multiple RCAs to the Denon, meaning the output from the source will have already been converted and will be analogue in nature before it gets to the Denon.

I hope this helps. I'm sure others will add to this discussion.
If you have enough video inputs on your TV, you will always have a cleaner video signal by avoiding adding extra components in the signal path. Conceptually, video switching can be helpful if you don't like having to separately change your TV to the right input *and* your receiver. I.e., you just click "DVD" on the A/V receiver instead of clicking "DVD" on your receiver and then selecting SVIDEO1 on your television. I use a theta casablanca to switch video as well as audio and do find it easier.

Come to think of it, however, if I remember right, AV receivers don't "switch" or convert s-video to composite (single RCA), so you will need both connections from your receiver to your TV and may have to do a little TV adjustment anyway as you go from s-video sources to composite sources. (This is where the Philips pronto comes in handy). I don't think there are many devices, if any, that switch component video and can't think of why you would want to do that anyway.
Optical cable is used to send 5.1 or more channels of sound, not for picture. Atleast that I have seen before. Typical video transfer cables are composite (RCA), S-video, and component (Red,Green, and Blue Cables). A better connection would be directly to the TV from the source. Component is the best choice for connection of video at this point in time. The less components in the chain, the better off you are. I don't own a surround reciever, but I believe the reason for the multiple video inputs on the back of the reciever are in case your TV doesn't support multiple inputs. Hope this helps.
Thanks for the answers I really appreciate it! In fact I got more of an understanding from your responses than from at least 10 visits to Sound Advise and Best Buy while purchasing my TV and stereo equipment.
I was talking about optical for sound only. I gather that optical was the best, coax next and then RCA but that is from the people making the connectors and I didn't know if it was because the optical was the most expensive or if it was because it was more practical. For video I use the component cables for the psx2 (it does have optical out) to the TV and plan on using the component cables for the direct TV as soon as I get a HDTV receiver and there are enough channels in HDTV to make it worthwhile, otherwise I use s video connections. I guess I will rum directly to the TV as I only have three components so far. The DVD goes to the CD plugs on the amp and the PSX2 is going to the other DVD on the amp. I will then run component cables from the DirectTV to the component #1 and the psx2 to component#2. I guess I’ll have to get a component switch box because I only have 2 of the inputs on the TV or I could use a S-video line foe either the DVD or the PSX2. Is there much difference between the three separate component cables as opposed S video hookup? To tell the truth I can’t see any difference so far. But have heard its much better? I’m not sure I understand what was referred to as video switching or why I would need to adjust the TV when using a RCA connection and then using an s-video connection so if Edesilva reads this post could you please explain that? Also, what is a Phillips pronto and a theta casablanca? Thanks again for all your help. Charlie
