AJA plus Larid/Spilter through a source selct
Working in a new place, they have FCP, fire wired out to a Digital Expander Module, with 2 channels on it to switch between to CPUs..
Then it is run through a Source select, to switch between Beta and DV, then through an AJA..
Im getting a lot of hicups, and dropped frames..
Just trying to get a feel from everyone, on whether there are to many devices hooked into one, or if it might be an software issue..
Driving me nuts cause I have an AJA for peronal use and never have any problems..
Any thoughts or advice… -

If you do crap like this, you will encounter the problems you are running into. It is simple to simply hookup the single firewire cable from the AJA box into the CPU you are working on, with no issues. When you want to hook up to another CPU, simply change the cable.
I have no idea of what you are refering to as a “digital expander” – nor do I care. Your “dropped frames” issue can be multiple issues, and you have not described your system in detail – we have no idea of what type of drive arrays you have, and how they are hooked up. If you are using Firewire 400 drives, and they are in this Firewire mess, then you will most certainly have problems.
A nice boring Laird or TecNec firewire patch bay will allow you to route
your single AJA product into several MAC G5’s. If you want to pop in a DV VTR into the firewire port, you can do this thru the firewire patch bay.Your source selector is confusing to me. Laird makes various audio/video
source selectors, and they also make a DV transcoder. The Laird source
selector can switch baseband audio/video signals into your AJA I/O, but you CANNOT use the Laird DV transcoder product at the same time you are using the AJA I/O product.If you would like more details, you will need to provide more sysetms information.
