Um...no, no it's not. My computer is quite fast and it's only my graphics card that blows goats. The framerate for the games I play on it are pitiful indeed - or it could just be all the mods I installed...
I explained this in last week's show as well. It's the spaces in your mp3's titles. That's the reason. It's not a mystery. The mp3 titles have to be one line with no breaks in it or the segment will error out in external players - except for Quicktime. Only our site's internal player will play it with title spaces.
How do I know this for sure? Because Wayne called me on it in MMS-159. I made the same mistake and when he told me about the title spaces, I fixed them and every show has worked fine since.
Just fill the spaces in the mp3 titles of your countdown shows with underscores (or whatever) as I did for this one and all of them will play in any external player.
