you'd have to give more info about your computer for us to tell you for sure, but you are probably trying to install leopard on a computer that shipped with snow leopard, or a newer version of leopard than is on the cd.
 
Mac is used

Retail dvd bought in 07 from Amazon.com

Do you know what exact/specific Mac it is? Maybe it is like the previous posters have already written, that the version of Mac OS X on the Leopard DVD is older than the version of Mac OS X that came with that Mac, point releases included, meaning you can't install Mac OS X 10.5.5 on a Mac that came with Mac OS X 10.5.6 for example.

Btw:

Boots retail dvd but install fails:-(
 
Giigabit G4 upgraded to 1.6 GHz

Power Mac G4 I suppose.
Hmm, is the Mac OS X version on the G4 still working, thus you could boot into it and see, if it even recognises the Leopard DVD?

Btw, how did you upgrade the G4 CPU - with an accelerator card or the actual CPU, as the original GB G4 came with 400, 450 or 500 MHz, thus not fulfilling the Leopard requirements?

Do you have another Mac with Firewire and SuperDrive or ComboDrive and able to boot it into TARGET DISK MODE and use its ODD?

At what point does the installation fail exactly?

It’s running tiger now I got a maxpower 1.6GHz card I have my mac pro

Hmm, that card is meant for that PowerMac G4. Does the 1.6GHz show up in About This Mac?

If not, that might be the reason why the installation fails, at whatever point it does that, as Leopard requires a G4 with 867MHz as a minimum and the MaxPower card might not be recognised by the installer. But I don't know that card, maybe the documentation, that came with it, can help you out?

Btw, when you write
I got a maxpower 1.6GHz card I have my mac pro
does that translate to "I have a MaxPower 1.6GHz card in my G4 PowerMac" or how is a Mac Pro involved in all of this?

It sees 1.6GHz & the mac pro is mine. On the retail dvd it fails to verify the inttall package

Test the Leopard DVD via Disk Utility and use the VERIFY DISK button* the DVD.
* select the inserted Leopard DVD instead of the "green" Macintosh HD in the below image

Btw, Mac Pro is the name for the desktop tower using Xeon CPUs by Intel, PowerMac is the name of the desktop tower using G3, G4 or G5 CPUs by IBM.

I burned Leoprad onto a DVD R+dl with Disk Utility went fine but skipped disc verify.

So either verify the disk now (as it may be bad) or consider burning another copy and letting it verify. You may have a bad image, or simply a bad burn.
