Thanks for the info guys. Will try pausing then rechecking pin and see if that works for me. Wish I know C++ seems to be the universal langauge for a lot of Microcontrolers out there. Let you know how I make out.

DVD-R

One thing I found that worked is to burn at a slow rate 4x or less. Same movie and same media, burn at fastes rate , when played will freeze. Reburned at 4x it plays just fine. Also media manufature makes a differance, I found Maxel or Sony seam to be the best for this issue. Hope this helps.

Re: How to size Transformer

Went to the other plant and found the origianal curcuit. Looks to me that they are using an IGBT (G7) with another # Q665 MEX and the bulb is only 150 watts then going through a mirror then colored lens. Is there a way to test this couponent?

Re: How to size Transformer

Sorry I don't know what kind of scope this is yet, I'm working on second hand info. I thought this was going to be a simple DC supply, but it brought up the question of transformer sizing which I have come across before. Today or tomorrow I will go to the other plant and see for myself.
