Re: [Motion-user] Motion-user Digest, Vol 30, Issue 5 error bttv card

[gudy <jaz...@gm...>]

what possibly happened with your card is esd(electrostatic discharche)  
dammage its typical with that after a few hours/days you get latch up of  
the electronics. make sure your pc and all stuffs is properly grounded and  
that you ground yourself before touching cards, or i/o connectors.
now a days many electronics work on 1.2v and 2v is fatal...its very  
difficult to design the proper esd protection for it...huu with a simple  
multimeter in resistance/diode test you blow up the electronics already...

warm greetings from Saigon :)
