When trying to play inline mpeg's in QT7.2, safari stops pinging servers

Question

i have 10.4.10 and updated to QT 7.2. now cant watch anything with the file extension .mpeg. if i try to view any .mpeg movie, safari tries to load the page, then safari wont load another page or ping another server untill i quit and relaunch it. other web apps work fine though after this happens. only if i want safari to work again i have to relaunch it. then it works fine. ive done every update in software update. repaired permissions. looked through the discussions and found other problems similar to mine like the no audio QT7.2 issue, and the "Plugin.webplugin" thing. tried it. that doesnt help. seems like lots of people are having issues but none are exactly like mine.
i found a work around last night but dont like it. i go into QT preferences/MIME, MPEG, then open the triangle and disable "MPEG Media" on the bottom. this fixes the safari not pinging thing but saves every mpeg to my hard drive and i cant watch anything in safari. kinda lame. not even apple.com/trailers!
actually, i had this problem a few months ago when QT 7.2 came out & i solved it by doing an archive and install to get me back to an older version of quicktime and OS 10.4.9. everything worked great and i went on with my life... i vowed to never update again, but because iLife '08 came out and requires QT 7.2, i had to do it because i wanted to mess with the new garageband, and im suprised Apple still hasent fixed it yet. i mean, in the billions of megabytes of java and security and qt compatibility stuff, they didnt fix this in all those updates?
i have a ibook with 10.3 that also works fine with my cable modem. my macmini works fine with my internet connection untill i update to quicktime 7.2
i have an intel mini 1.66, 10.4.10 and QT 7.2. have flip4mac and divx installed as well. any help would be appreciated. thanks.

You might need to update some settings:
These are the downloads and the settings you need in order to view/hear pretty much everything that the net can throw at you: The setup described below has proved repeatedly successful on both PPC and Intel macs, but nothing in life carries a guarantee!
Assuming you already run OS 10.4.9 or above and have Quicktime 7.2, and are using Safari 2 or 3, download and install (or re-install even if you already had them) the latest versions, suitable for your flavor of Mac, of:
RealPlayer from http://uk.real.com/player/
Flip4Mac WMV Player from http://www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx (Windows Media Player for the Mac is no longer supported, even by Microsoft)
Perian from http://perian.org/
Adobe FlashPlayer from http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash
In Quicktime Preferences, under advanced, UNcheck Enable Flash, and under Mime settings/Miscellananeous only check Quicktime HTML (QHTM).
In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them).
Important: Now repair permissions and restart.
The world should now be your oyster!
You should also have the free VLC Player from http://www.videolan.org/ in your armory, as this plays almost anything that DVD Player might not.
