QuickTime X can't use .srt files

For some reason, ever since Apple released QuickTime X, QuickTime won't open files with an associated .srt file anymore. I get the error QuickTime can't open it and if I would like to open it in QuickTime 7. And the strange part is, the .srt files are working with Preview. I have Perian installed correctly. I don't mind using QuickTime 7 and I know VLC is far better in using .srt files, but still. This question intrigues me a lot. How can I make QuickTime X work with .srt files?
