Thanks y'all!
I have a fresh version of flash on this machine and have tried Safari and Firefox. I tried to get in again tonight. Same story. Hangs at 100% loaded.
I could try other browsers, but when the other DXD channels work and it's just this one that fails to load; I'm guessing that won't help.
I've gone ahead and submitted a bug report about it tonight. Was it the correct path? Who knows. Will someone get my report and respond? *Shrug* Will they fix it? I hope so.
