[X4U] Quicktime problems

[LA Licata]

Dear list,

lately, I have been unable to view a quicktime movie embedded in a  
Safari window. I get a gray'd out Quicktime symbol with a question  
mark in the center.

I thought this was a Safri 3.0 problem but I get the same problem  
using Safari 2.0.4

I am running a 17' G4 PB, system 10.4.10, all other software up to date.

Reloaded Quicktime 7.1.6 and  re-installed with its security update.

Also reloaded Flip4Mac.

Problem continues.

Any suggestions very much appreciated..
