Flash player 10.1 still not working (more information).

Question

A few months back, I made a thread concerning my situation of specific flash content not being played.
I have returned, with hopes that my trials and tribulations may provide more insight into my problem.
Basics
Windows XP 32bit (v2002) - Media Center
Service Pack 3
Audio and Visual drivers up-to-date.
Web Browsers
IE8
Google Chrome (6.0.472.62)
Mozilla Firefox (3.6.8)
All of these are running on the latest Shockwave and Flash players.
The Problem
Various types of Flash content cannot be played. This is what I have been working on for the past few months.
1. YouTube works fine.
2. ShockwaveFlash objects that are located on my hard-drive play fine.
3. Embedded Players  (most commonly MySpace and JWplayer) will often freeze upon page loading, or will never load (progress circle spins forever).
These issues, however, were avoided upon using Firefox to view the pages (I was originally using Chrome). An new version of chrome was just released, and it APPEARS to only have problems with the MySpace player. Haven't tested this yet, though.
Video streams are completely out as well (except YouTube streams).
These embedded videos on the video-indexing sites I visit may never load depending on their type, but they will often work normally when viewed on the site that owns the player.
4. Embedded Objects (such as flash games) will vary in playability from site to site (an embedded version might not work on one site, but another site which hosts it as an executed file by itself will).
The flash games will play through intros, but freeze (right-click "play" box becomes unchecked) upon reaching an interactive menu, or any sort of interface.
5. I have tried fixing the Global/Local Settings and all the stuff there. I have tried changing the amount of data storage allowed for sites, but the flash games WILL NOT set any data. This makes sense, since they are not even running...
Previous Advice
"Post the files from file:///C:/Windows/System32/Macromed/Flash/"
A folder called FlashPlayer Trust, and these files;
Flash10i.ocx ~ FlashInstall.log ~ flashplayer.xpt ~ FlashUtil10i_ActiveX.dll ~ FlashUtil10i_ActiveX.exe ~ install.log ~ NPSWF32.dll (version 10.1.82.76)
"Check in Tools & Extensions and make sure Shockwave Flash Object...ActiveX Control...Flash10h.ocx is listed and Enabled"
Shockwave Flash Object - Check
get_atlcom Class - huh?
Shockwave ActiveX Control - Check
Did not find Flach10h.ocx          I guess this is where a warning light should go off in our heads.
Older Versions
Since this all started when Flash 10.1 came out, a logical assumption would be that downgrading my version number would solve the problem.
It did not. I tried a good half-dozen of the archived versions (none below 9.0 or not for my OS) and nothing happened. Really, nothing. Same old problems.
Other Stuff?
Disabling hardware-acceleration did nothing. just putting that out there.
Please use this thread, as I tried hard to make it more clear and organized. However, if you wish to read the old thread;

Answer 1

Hi, Norton normally just Disables the Windows Firewall and runs their own; first I've heard they gave a choice.
So are you running the Norton Firewall or the Windows?
Several things are going on, having your Internet Security set to Medium-High blocks ActiveX Controls from working. Guess what the Shockwave Flash Object is? It is the ActiveX Control in your browser that works with your Flash Player files and the websites so you can view Flash Content & Videos.
Then the Norton Toolbar, the Intrusion Prevention and the NCO BHO conflicts with the browser and FP. Now the ControlInstaller Class and the PSFactoryBuffer must be new browser add ons from Norton. I'll research them and see what they are about.
Your Norton add ons, Norton Firewall, the RP add ons and your Security Setting for the Internet Zone are all conflicting and blocking Flash Player Content and Videos from the Websites.
In other words Flash Player is trying to work for you and all of those just mentioned are saying, no way!!
So I guess you'll need to decide if you want to use Flash Player or be extra extra secure.
Let me know,
Thanks,
