Update time. Here is a video that goes through the update repair process,
The step that worked for me is going with this download link https://support.microsoft.com/kb/3138612
(option 2 in the video) and you must select either the 32 or 64 bit version to match your needs. After running the downloaded patch, the update process has worked flawlessly. Once all of the necessary patches were installed I re-ran the Media Center channel setup and I got video again on all channels.
Next, I found a riser card that has 3 slots, without cables that allowed me to use all three slots. On Ebay one can be found by searching with "PCI 301-B, 3-slot PCI Riser Card, Right Angle (New in Static bag)".
There are a set of jumpers that you need to set but it doesn't take long to figure out. So now I have both tuner cards and the wireless card functioning properly. I tried to install a third tuner card but Media Center stated I could have a maximum of 2 tuners. If I missed something in the configuration let me know because I don't need the wireless and would really like the 3rd tuner card. BTW, if anyone is looking for one of these cards, pay close attention to the direction because you need a Right Angle card. I did purchase a 3 slot with cables but with my motherboard I can only use two slots so it'll be a good spare. Almost forgot, I have to make a couple of small adjustments to the riser card chassis but that won't be hard either.
I have 6 bad power supplies that I will start repairing later. Several let their magic smoke out and a couple lost one of the voltages. I have 1 good one left in a Z565 that I'm praying will last another week. I have ordered 2 "Replacement Power Supply for DPS-160QB HP Pavilion Slimline SFF P/N 5188-7520" that are rated at 350 watts for $24 each. They are smaller than the originals, will fit into the original position, but will need the long 8 pin harness added (there goes another hour). I think it will be enough power. I'll be adding wires and testing once they arrive in a few days. I'll take pictures and post the results later.
One last thing. There are PSU's available on Ebay for the Z5XX DEC's. These are old stock units and don't last long. I purchased 4 and was able to get replacements for 2 of them but they were very bothered by my second claim. The two replacements have since failed. It's very possible the capacitors are failing simply due to age.
