Yamaha RX-V3800 and component output question...


Hi guys,
See if I can tap into someones brain when it comes to this amp.

I have some older equipment that dont have HDMI output. Mostly relies on the component output and some HDMI’s, but having issues with one component video output from one of my equipment.

Now, the problem I have is this...

I have a tv hooked up via component output (YPbPr) feeding all output going into the amp via component output to this tv.

In addition to this tv I have this overhead projector hooked up via HDMI (This projector have a straight feed using HDMI, but I also have a component video and low res S-video feed to it)

The amp (Yamaha RX-V3800) support all these input formats along with HDMI, component video and S-video monitor output.

Problem:
One of my old VCR/DVD players dont support HDMI and as a result of this I used the component video going to the amp.
Works perfectly going to my tv, but nothing is fed to my projector.

The tv received a full 1024i resolution via component output from the amp.

Same hookup (with the difference of connecting both component and HDMI) from my xbox works perfectly on both tv and projector.
Same with my set top box (component video and HDMI) 1025i res to both outputs

The dvd however where I am limited to just component video, sends full res to my tv but nothing to my projector.

Even tried to bypass the tv component and hook up the projector component video to the amps component output and what it ends up with is some 512p or so resolution - a far cry from what I expect.

I have confirmed that the amp configuration under "Mandual setup" -> "Video" -> "Conversion" is turned on - yet nothing being fed to the projector.

All but my vcr/dvd player have both component and HDMI output and they all work - Seem like the lack of HDMI output from the vcr/dvd prevents the component video signal being fed from the amp HDMI output through to the HDMI input fail.

Any suggestion how to work around this would be appreciated. As it stands now I cant watch dvd’s on the big screen - only on the small tv screen.

Wonder if a component output splitter similar to this might be a solution that in effect could feed the component output in parallel to both tv and projector component input on each device ? - Just not sure if the handshake from tv and projector would be out of sync or cause problems ?

Sorry - a typo - the resolution I was meant to state is 1080i
component video may be "old technology" but as for providing optimal picture resolution its just as good (if not better) than HDMI = If you dont need sound embedded theres a lot less chance of component video being incompatible with various devises since HDMI protocol standards have been (and still is) updated (which may cause older and newer components to be incompatible - Theres heaps of discussion thats been going on over many years now and the final judgement of HDMI or not is still open
also, I do think theres some kind of handshake going on via component input though - I can see my projector searching between the whole resolution spectrum when no component video signal is sent but the projector have been set to component video on the remote - But I think it might be worth a shot using a component cable with split into two parallel outputs

The idea of "handshaking" is a two-way communication coordination.  This is only in specific digital protocols, such as HDMI or Ethernet.  Component video is completely analog and it's one direction only.  The DVD/VCR is just spraying out continuous analog waveforms with no expectation or understanding of what's happening on the receiving end.  When the projector received component video, it may go through an exercise of analyzing the waveforms to determine resolution and frequency, as well as to lock onto the screen refresh timings.  However, there is no communication or "handshaking" back to the DVD/VCR.

One thing that you could try is take your DVD/VCR and the component video cable currently attached to your TV and bring both closer to the project.  I assume the "TV component cable" is a shorter cable.  See if the projector will accept component video directly from this. 

Then go from there.   It could be the "long component cable" is not working well.  Or it could be that the V3800 is not re-sending component video in a way that works with the longer cable - or it is not compatible with the older 1080i component video format.
