Strange QTSS Behavior: Whacked Playback after FIRST Connection (requires reboot of Mac Client)

Hi All,

Just thought that I'd throw out another strange behavior that we're seeing on QTSS. Has anyone out there seen this problem?

I have a client that is running a couple of different machines that we can get this streaming failure pretty much every time. Basically, if he clicks on a link to stream a movie, it'll play just fine the first time. However, if he clicks on the same link again, or any other link on the page, ALL subsequent streams will play back inconsistently. We'll usually get all of the audio, but the video is choppy, or simply doesn't play anything but the first few frames. The only way to get a clean playback is to reboot the machine. He'll then click on another stream, and gets a perfect playback the first time, and sure enough all subsequent streams are toast.

We've tried this with our own content and just recently setup the sample streams that Apple provides for testing of proper setup of QTSS. Same results as above.

I've watched his connection on web-based QTSS Management Connection page and can watch the connection. Sure enough, the first connection shows and and the bit rate kicks in and begins streaming appropriately. The second time I can watch the connection and can immediately see that the bit rate is a fraction of what it should be. We are getting 0% packet loss - so bandwidth doesn't seem to have anything to do with this problem.

The one client that we tested this with today is a Dual 800Mhz G4. OS 9.2 QT player is 5.0.2. Browser is IE. Not sure of the specs on the second machine other than it's a laptop. Will get those specs if anyone deems them necessary.

Should note that he had another system sitting there in the same room/network that we tested that worked perfectly as it should. It's a 1.25Mhz G4 running OS 9.2, QT player is also 5.0.2 and Browser is IE. Go figure.

Any clues or thoughts on this one, I'd be GREATLY appreciative. This poor guy is going nuts trying to view content, which causes ME to go nuts when he can't.

Thanks...Bob
