In Arcade_OSD, you can either see a "p" or "i" next to the vfreq value, that stands for progressive/interlaced, but those values are only valid if the drivers/OS are reporting them properly, so I wouldn't trust them. Interlace is obvious when you see it, anyway.
It might happen that the tri-sync utility is working for some higher resolutions but didn't update the 512x448 one. Have you noticed if 640x480 is progressive?

Thank you for more detailed help. I'm going to experiment with different software/hardware combinations and see if I can find the root of the problem.
A friend of mine is going to give me an ATI Radeon X1300 to see if I get the same results as with the Arcade VGA 3000. For just MAME games is there any advantage to purchasing a ATI Radeon X600 XT or does the X1300 give me everything I would need?

The X600 XT is the most powerful model in the R300 series.
The X1300 is the least powerful model in the R520 series.
In actual use, they're probably about the same, performance wise. The X1300 supports a slightly newer version of DirectX 9, but that should make little or no difference for running MAME unless you're trying to use some of the new HLSL features, though the X1300 is too slow for that anyway. You can compare specs here...

I only suggested the X600 XT because R300 series based cards are known to be reliable, compatible, and cheap.

Hi msingleton1977,
The X1300 (actually all X series but for the older ones X300-X600) have problems with low pixel clocks. This means that, although these cards work with Soft-15hKhz / GroovyMAME, etc. they can't do low resolutions, you need to scale them horizontally, like 320x224 -> 640x224. This has no visual effect, it looks just fine in GroovyMAME, but I just want to warn you about this. If you can, go for one of the X300-X600, or one of the HD 4xxx family ( HD 2xxx and HD 3xxx have the same problem).

I added a note to my mirror of the CRT_EmuDriver page...

For best results, a X300-X600 or HD 4xxx card is recommended.
