I am unsure if this is a security issue, a networking issue, or what.

For years I have been listening to austinriffs.com. One clicks on "To The Shows" which takes you to a list of the shows and then one clicks on a show. At this point a blue "Apple Quicktime logo thingy" shows up then turns into a typical little music slider bar.

But recently instead of playing the approximately one hour show, the slider moves across very quickly (plays with sound for 3 or 4 seconds) then stops and no more sound.

I recently installed Zonealarm Pro and I think that the problem is related. I have ZA, Norton AV, and Firefox NoScript extension. I have attempted to give that URL full clearance in each one of these. What is perplexing is that it plays at all even if for only a few seconds. I would think that it would either play normally or not at all.

What gives?
