    looking for trash files
    sounds like the signal is getting lost in the adapter chain.

    i think THIS is what you are looking for. has worked for me in similar situations anyway... best of luck!

    Yup, use the link posted ^.

    The Mini-DVI-->DVI adapter only carries DVI-D (digital signal) and cannot be further converted to VGA by a cable connector converter alone. You're need a Digital-to-Analog converter, which is $$.

    There is your issue. You cannot go Mini-DVI-->DVI-D-->VGA just by cables, sorry for your confusion OP.

    Just adding one more thing; if using RCA I'd advise you not to set the resolution above 1024x768, and recommend 800x600. You won't be able to see increased detail in anything above 1024 and I usually find it gives everyone present a headache trying to read small fonts as it is.

    Beyond this, a lot of older tube TV's don't even like anything above 640x480. Going higher just makes things smaller than the tube can reproduce well and makes for pretty crappy image quality.

    reason being that DVI is Digital, hence D.VI and VGA is analog video. So it wouldnt of worked if you gave it a massage and asked it pretty please! :p

    Hi just to clear up the confusing surrounding this issue your having.

    DVI comes in two formats, DVI-D (Digital) and DVI-A (Analogue).

    What you have is a mini DVI-D port, which is not able to convert to the analogue based VGA standard, this is where your signal is being lost.

    To be honest, connecting a laptop to an analogue TV is not going to be blazing (low resolution+high screen size = bad image quality) so I would advise just leaving it be, and maybe using am LCD panel of HDTV later down the line.

    If you still want to connect your Mac to your TV you will need a digital->analogue converter with DVI inputs and RCA outputs. Over here in england such a device would set you back about £50 ($75ish)

    Hope this helps!!
