voltage levels of PAL vs NTSC composite signal

[quickfamily]

Hi,

I bought an ATI TV WONDER VE in the USA to capture my PAL video tapes. The box stated that it would only work for NTSC but I managed to get it to work through the composite signal input using a PAL signal. However, I sometimes get audio sync problems and the really weird thing is that this seems to depend on different tape manufacturers that I put in the camcorder. I thought that maybe different tapes record at different signal strengths and so the resulting output signal might be stronger with some tapes than others.

So my question is, does the composite signal input have different attenuation characteristics for a PAL vs NTSC card? If it does I'll buy a PAL card over the internet in the UK and get a relative to ship it to me.

The card should work fine for PAL. Composite PAL and NTSC have the same voltage peak to peak, only the black level is at different points. NTSC have black at 10IRE higher than PAL. I capture PAL and NTSC all the time via the same hardware, and have no problems.

Hi guys, I live in Australia and bought a ATI AIW Radeon AGP NTSC 32mb recently over the net from the US. I can't tune PAL at all. I can't pick Australia from the Broadcast Selection either.
Have they sent me the wrong card or is it the software???

Is there much difference between a ATI TV WONDER VE and mine? I am desperate for answers as the company that i bought the card from will not respond to my emails....%$^#@*
