Well, apparently it's not quite that simple. My DA DP 533 won't play Youtube videos smoothly on Firefox, Safari, or Opera with the GeForce 6200 card. The machine has 1.5 GB of RAM to boot, and does well with normal browsing. My Ubuntu dual-core machine plays them fine, so it's not the internet connection. Intriguingly, the G4 plays commercial DVD's just fine, which makes it sound like something other than a CPU or video card horsepower issue. Does anyone have experience using a PCI LAN card, rather than the built-in one? Is this a software issue? - Michael B. in Cincinnati On Thu, 2009-10-15 at 12:00 -0700, g4-request at listserver.themacintoshguy.com wrote: > Re: Video upgrades for PowerMac G4 dual (Tex Weinberg) > (Mike Bechtold)
