Actually I figured this one out on my own, so I feel a little better.
The IPC 1100 auto detected that my TV was 1080P and set the output resolution to 1080P60. However, it appear that in doing so, it was also trying to push that resolution to the component output interface, which the Slingbox can't handle, (Slingbox only does 1080i or 720P for HD).
Anyway, I went into the diagnostic menu on the IPC 1100 and set the resolution to 1080i and the Slingbox started displaying video immediately.
What's weird is, I didn't think component could do 1080P but whatever....I got it to work, so I'm good.
Diagnostic menu is still accessed by: PWR=>OK=>Menu. The other diagnostic (view only status) menu is accessed by: PWR=>OK=>OK.
Don.
