OS 10.3.9 and QT Pro 7 = no video controls

Question

I went against my normal behavior and obeyed when the computer said to upgrade from QuicktimePro 6 to Quicktime 7.0. Then discovered I had to pay another $30 to make it be the Pro version But no video controls are there - apparently I must first buy various upgrades, like a new computer, it sounds like from the forums. Video controls are why I originally bought Quicktime Pro. I could have gone back to v.6 from 7.0, but not if I'm as high as 7.1.3 (I am). At first I thought I could go back to 6 Pro and use the Pro 7 license for the husband's WindowsXP upstairs. You can't even use the license key in Windows, though.
I think this is outrageous. Does Apple know how angry people get when they feel tricked? Most people don't have money to keep buying lots of computer stuff. Or want to be eternally tinkering.
Is there a (preferably free) program that will brighten a .mov, .mpeg-2, .mp4...or adjust contrast? I couldn't make mpeg streamclip do it yesterday. Oh, I did try exporting .mov to .mov to make those adjustments, and the result was a bad degradation.

Answer 1

I didn't miss having Quicktime 7 for 2 years untill I encountered a video that wouldn't play without it, as I recall. I was making a lot of videos and wanted to try new features, as well.
Yes - I thought I would register with the same registration number I had before. Why worry if Installation says older Pro versions won't work - wouldn't the new one be all that and better?
The info page http://www.apple.com/quicktime/player/mac.html says you'll have the a/v extra features if you have Tiger and a graphics card. I thought the other way to have the features would be to get the Pro version, like it worked for Quicktime 6. Bad assumption. Do the auto-updates with checkboxes that suddenly appear on our screens even send us to that info page?
For simpletons (we are legion) they could say for instance "your computer may not have enough power for the free Quicktime 7 a/v features or smooth streaming video (apparently) etc, even if you're running Tiger"......Quicktime 7 is simply labeled, in Versiontracker for instance, as designed for system 10.3.9 and up.
I didn't mind paying the $30 for QT7Pro version, but was surprised that I ended up with less useful everyday features than I'd had. I felt tricked, but I don't read slowly and carefully enough, and I know Apple wasn't trying to trick me, just push me toward their store.
fflynn - thanks for the idea. It sounds brilliant. Setting up a separate volume - not sure what that is - sounds scary, but I'll learn today.
