    Further to my post http://www.avforums.com/forums/showthread.php?t=238516

    I noticed in the specs for the Yamaha receivers that they are HDTV compatible and are happy with 720p and 1080i....

    I just assumed that any component feed whether it be 720p/1080i/480p etc... would be output from the receiver in the same way.... (the receiver simply switching between inputs?)

    Is this not the case though? the Panasonic SCHT17 speaker set does not mention HD resolutions but it does have the component connections...

    Would a receiver generally alter the AV input or do you think the output from the Panasonics would remain the same?

    This will change according to the manufacturer's adherance to the published. You need to check with your retailer so that you can take the box back when the inputs have been vapourised

    Thanks for the reply... I'm not sure I understand what you mean...

    Adherance to the published....... standards?

    Vapourised? do you mean when component is generally replaced by for example HDMI...for the moment I'm happy with component... I just don't want to find though that in the HD modes that the display is out of sync for example.

    Ideally the Component Inputs/Outputs will have their bandwidth listed in the specs. The higher the better. For example, most Denon models now have 100 MHz but 50MHz should also be sufficient for HiDef.

    Ah I see...thanks for that... I think the Yamaha and Panasonic specs do quote these so I will compare them. :smashin:

    Hmm, checked the specs on the Panasonic set - SCHT17 and they only seem to state...

    VIDEO SECTION (SC-HT17)
    Output voltage at 1 V input (unbalanced) 1±0.1 Vp-p
    Maximum input voltage 1.5 Vp-p
    Input/output impedance 75 Ω

    THe Yamaha RXV357 brochure states this though

    HDTV Compatible 2 Component Video Input
    and Output Terminals
    Component Video inputs offer higher picture
    quality, for use with units such as DVD players
    that have Component Video output. The
    frequency response of the component video
    signal is 5Hz – 60MHz, making it compatible
    with HDTV (720p, 1080i). The RX-V357 allows
    you to connect two different components for a
    choice of high quality video sources.

    According to their specs, it will be fine for Hi-Def (720p & 1080i) video switching. :)
