Xbox Live Silver + Jtag Options

[jigglywiggly]

So... I just want to download some media codec packs for my jtag, to watch on this lovely new tv. Unfortunately, most of the videos don't play/slow, even with tversity. So is Microsoft devious enough, to just blow the efuses if I go online? I never removed the r6t3 resistor, as I finished up my 360 before I did that. I know they overwrite your nand... but I'm running freeboot, will it matter? I'm guessing no.

I'm not going to try to do this without protection, but can I just write protect my nand, and solder the two points near rt63, and keep creating xbox live silver accounts? I just want to browse the marketplace and stuff.
