> but a DVD player bought
for your TV, How do you hack that?
There are different ways, depending on the player. Some you can
"hack" by pressing a sequence on your remote (like a video game easter egg),
some require a firmware upgrade which can be flashed (ie put it on a CDrom and
put that in your player), some require a whole new chip.
and some might show up here that aren't listed in the above:
My standard DVD player requires a new chip for region free so I went out
and bought a cheapo player for under $100 that allowed a firmware upgrade.
The only way you can "screw yourself" is if something goes wrong with the
flash upgrade -- like a power surge, etc. Flashing and remote sequences
are almost always reversible (and I say "almost" because there might be one that
isn't but I've never read about one). Obviously replacing the chip is
permanent.
