Trouble with RSS feed

[jgold723]

So far, the player seems to work fine, but I can't seem to get it to
display an RSS feed from my YouTube account. I've tried two different
"strings," neither of which works:

Can anyone tell me how to format an RSS string that will work in this
player?

Thanks,

John
