<div dir="ltr">Don't use the +12 line. It will likely destroy the unit. I am very surprised that the internal +5 supply in a PC ran out of current. I could understand that if you got the +5 from a USB cable but not from one of the molex cables. Maybe the wire is too small or you actually hooked up something wrong.

So, I made my attempt at a cable to replace my wall wart and my <br>
recordings are not working so good. After re-reading this, it appears I <br>
should *not* have used the 5V line even though the wall warts I have <br>
show 5V @ 2A, right?<br>
<br>
Interestingly, the HD-PVR does power-on and is assigned a device <br>
(/dev/video5 in this case). However, I attempted a 4 minute recording <br>
and actually recorded for about 1 second. The "blue" light turned off <br>
every 4 seconds, then back-on again.<br>
<br>
So, use the +12V line and not the +5V line?<br>
<br>
