[mythtv-users] Fry my Equipment?

[Laura Thompson]

     I can read until my eyeballs fall out of my head, but I'm not going
to "get it" until I actually dig in and do it.  Verbage makes more sense
after a little hands on.  However, I don't want to permenantly damage
things during this learning process.
     For instance, I read somewhere that if I don't set my resolution
correctly in XF86Config-4, I'll fry my TV.  True?  Does it have to be on
a seperate box, or can I install it all on my desktop PC?
     Absolutely don't mind messing around while I figure things out
(hardware, software, setup, etc), just want to make sure I still have my
equipment when I'm done :)
     Craveats? Gottchas?

Thanks for any advise!
