CAN'T GET HDMI CONNECTED VIDEO/AUDIO(tv) TO SYNC WITH AV UNIT'S AUDIO.

Here are the the way things are connected. I'm connected this way for now until I get an AV unit with HDMI connectivity. 
AV Unit: Yamaha RX-Z1 Highend, but pre-HDMI

(Video 1 - Samsung LCD) DVD to HD TV via 20 ft HDMI cable - Video and audio coming from TV are delayed behind the AV unit, even when delaying the AV unit 160ms which is the max. actually it had little or no effect.

(Audio) DVD connected to AV unit via 5ft monster RCA cable.

(Video 2) DVD connected to a Sony Trinitron via 5-6ft S-video cable. The video or audio from this unit are not delayed at all with AV unit set to 0ms delay.

In essence the main source is the DVD delivering audio and video to the HD Samsung via HDMI. The Yamaha gets it audio from the same DVD unit via RCA cable. The Sony gets it video from again the same DVD unit via S-video.

It appears the new technology is getting butt kicked by the old. I have a hard time believing that and I also have a problem believing the HDMI cable being roughly 15ft longer than the other cable types involved could add 200-300ms delay especially when HDMI is supposed to be soooo much faster. They wouldn't make 20ft and longer HDMI cables if they caused such degridation in performance which is uncorrectable by the AV unit. The DVD is a "nothing special" unit made LG, but hey it had an HDMI output so I tested with it until my HD-DVR arrives for broadcast media. The Samsung sits above a fireplace, so the HDMI distance cannot be shortened. I'm suspecting the LG DVD unit.

I do realize the right way is to all have source units (satillite, DVD, Blueray etc) go to the AV Unit, then run a single HDMI to the TV, but as I said that isn't possble yet.

Anybody have an idea what's going on with this?

Using the HDMI won't do you any good, since the TV will not pass the high-quality signal out the optical port.  So just connect the DVD video to the receiver with component and connect the DVD-audio to the receiver with the optical.  Then connect the receiver to the TV via component.  You won't lose any video quality over HDMI with this connection.  In fact, that receiver looks excellent, so other than simplied switching, I don't see any reason to get a new receiver (unless you're looking for the high end bluray audio).

Now a rant - I couldn't get the manual for Yamaha because their site wants me to register first.  What the heck is that all about?  Do they think people are going to violate their manual copyright, you know, in case we start building fake receivers.  Ticks me off.

I almost forgot - stay away from the Monster cable.  It's overpriced and gives you no better connection quality that a decent cable costing 5x less.  (Look at web sites Bluejeans or Monoprice.)

Are you saying that you have audio coming from tv at same time it's coming from A/V system?
Is the 5 ft Monster RCA cable connected to a digital coax output?

Since you don't have an HDMI receiver, there's no need for audio to pass over HDMI. You should have the HDMI from dvd to tv for video, and digital coax or optical from dvd to receiver for audio. The video and audio should sync that way. There may be a setting somewhere in the dvd player's setup menus, to send audio out, other than HDMI? The tv's speakers should be turned off, in the tv's menus. With home theater, there's no need for tv speakers.
Maybe someone else will chime in with an idea..............
Good luck!

The RCAs go directly to the AV unit coax port from the DVD now the DVR which was installed today Argh!. The DVR is doing the same thing or should I say the DVR didn't solve the problem. I should have clarified earlier that both the Samsung TV's video and audio are behind AV unit's sound output. I just use the TV's sound volume to demonstrate just how delayed the TV's audio and video are behind the AV unit.

It's weird. I have the old TV connected to the DVR as well via S-video and coax for audio, it's not delayed and works fine. It's just the audio and video at the end of the 20ft HDMI that's coming out delayed. I wonder if their is some sort of port setting on the TV that has caused this effect??? Time to review the TV manual and see...
