Users report an issue where they are unable to preview tracks and videos on the iTunes Store after the update to iTunes 7.0.

One reader writes:

"Installed iTunes 7 and Quicktime 7.1.3 on AGP PowerMac (500MHz) upgraded with Sonnet CPU board. Cannot see the video but do hear the audio from trailers in movie section of iTunes Store. Clicking on where the video should be, I can only see the outline of the area where it is supposed to be playing."

If you are experiencing this problem, try the two following workarounds:

1. Remove the following file:

QuickTimeH264.component

from the folder /System/Library/QuickTime, then quitting and re-launching QuickTime.

2. Look in the following folder:

~/Library/iTunes Plug-ins

for any third-party plug-ins, then remove them. Quit and re-launch iTunes and check for persistence of the behavior. You can then add the plug-ins back one-by-one (quitting and restarting iTunes between each move) to isolate the offending item. Plug-ins that have been identified as potentially problematic include OSS 3D (a tool used for real-time audio enhancement)
