I am running OSX 10.4.8 and Quicktime 7.1.3 on my G4; when I try to open a movie trailer or any files that used to play on my Mac, it now opens a page with nothing but the heading and goes no further. If I try to open a demo from the Apple.com site it tells me that Quicktime 7 is required, even though it shows up in the list of installed plug-ins...
Probably a simple answer (for those who know it!).

Plug-ins you say? Quicktime is an application. You don't have to buy Quicktime (but you may want to buy it in the future). You can download the Quicktime Player for FREE.

Yes, but as the OP mentioned the QT plugins for web browsers are on his setup which is needed to view audio/video media.
Depending on the setup they're located: ~[hm] or HD/Library/Internet Plugins/Quick Time Plugin.plugin and Quicktime Plugin.webplugin.
For the OP: which browser and do you have QTPro?

It's been on my machine and constantly upgraded; I've re-downloaded it just on the chance that would fix the problem. It has not...

I'm running Safari 2.0.4 and no, I don't have Quicktime Pro. Just the freebie.

Might try placing QT Plugin's prefs in the trash. Quit Safari first: ~[hm]/Library/ Preferences/com.apple.quicktime.plugin.plist. When you launch Safari a new one will be created. You can always put the old one from the trash back if need be. In Safari's prefs: Reset Safari & Empty Cache.
Its nice if you have a HD backup. At one point there was NO way I could view iTunes' trailer videos. Spent way too much time on the fix. So...used backup firewire Lacie external HD and booted from that since it was just backed up using SuperDuper-->formatted the internal HD and used SuperDuper to transfer all data to the internal and all was fine. The point: its nice to have bootable backup.
