Constant tearing in MPC and flash plugin!

I'm getting a huge amount of horizontal tearing in Media Player Classic that doesn't seem to go away unless I turn on D3D Fullscreen which creates a fullscreen playback that can't be minimized, with no context menu or on screen dialog and must be completely exited to get out of full screen. which is awful. It also occurs in the embedded firefox flash plugin.

I've updated my dX and video drivers,
how do I stop all this tearing?

Flash - does it happen when you move the mouse?
If so, could be the protected mode.

As for media player classic, not sure.
Perhaps it doesn't handle software rendering well.

I cannot offer help...only sympathy.

I built a custom HTPC on a $500 budget...and when I started playing media files...I got annoying amounts of tearing.

I researched the problem for days...trying every which software update and setting. Finally, I had to reconcile myself to using D3D mode in MPC.

I recently upgraded to from a 28 inch to 55 inch television...the problem persists. I suspect it's a video card problem...but I dread shelling out bucks for another video card and discovering the problem persists.

I would be interested to know who gets NO tearing...and what video card they use.
