I currently have a similar problem with a box, BT878 based card, two rca inputs.
It gets a black screen with constantly flickering flecks of colour on both inputs, on one it changes to a flat white screen more regularly than a black, no flickers when white.
Both do change back to a normal picture probably ... half the time I'd guess.
Very strange, I had thought it might be the card shorting somewhere, on the case, cables, anything, no luck there .... inconsistent power to the attached cameras .... nope ....
Both cables to run down the inside of a wall, passing quite close to a set of imbedded fluro lights used for illumination, they do get warm and increase the temperature of the cable somewhat. However they don't appear to be the cause, as there is no real correlation between when they are on and when it gets this strange input.
Yet to actually swap the card however, everything else has been replaced with known to be working elsewhere hardware.
Just thought I'd mention this, jog someones memory if they've ever had similar problems, and find out if this is very close/exactly to what Randy is also seeing ?
Regards
Colin Stubbs
