Reply to Numark DJ I/O and YouTube/Flash

I have a Numark DJ I/O when I can't watch YouTube videos with it; the videos stutter and play too quickly. Some other flash applications don't work well.

It took me a while to figure out that my DJ I/O was the culprit.

I can watch YouTube in HTML5 in Chrome, no problems there. But for various reasons I use FireFox as my main browser and it sucks to have to launch a new browser whenever I want to watch YouTube or play certain Flash-based audio.

First of all, a warning to anyone purchasing this sound card. This is an issue. Secondly, has anyone else experienced this and come up with a solution? Or it is time to upgrade my cheap sound card? I'm running a Macbook with Leopard.

Thanks in advance for any replies.
