Re: What's wrong here: deck, tape, IoHD or the operator?

[John Knowles] "PDATE: I have an HD monitor now, hooked it up via component outputs this time and was able to reproduce the panic as before (meaning the HDMI is not the problem). The settings were: Primary and sequence set to 1080i29.97, 720p60 clips on the timeline, SafeRT Video Quality set to MEDIUM. "

Before you do anything else- you need to reflash the Firmware in the IoHD-

Something is not right- I would start there BEFORE you yank the RAM

[John Knowles] " bought both sets of 1GB chips from XXX ; their memory has always worked well for me and it's not cheapo generic stuff. But I have noticed that Leopard is a lot more sensitive about certain issues (memory, graphics card) than Tiger was, so that may be a factor. "

Yes the newer machine are more sensitive to RAM issues- thats why 3rd party RAM is always been suspect. Just because it has "always" worked for you does not mean that it was Ok, just that your systems needs were not enough to cause errors. Doing HD is harder on your computer than dragging it behind your car- it is time for the hardware to be fussy if it is not getting what it needs from the system.

Since you are KP'ing - what does the crash log say ? { the apple crash log will have a line that says
"thread X crashed" and it will point to a likely cause- have you looked at what the log says?}
