Checking, no rush, on my open questions

[Hank Roberts]

I'm just checking because I haven't seen anything from the list in a 
while, due to my own other distractions.

I'm continuing to try making short stereo movies using two firewire 
cameras -- the two samples made under older OSX when things worked 
better are still available

  each under 1 meg, for "parallel view"

My open questions remain, here's all I know about them:

Driver betas:  I at the moment have removed all the IOX files (is there 
a complete list of what to uninstall and how?).  I still get crashes 
with EvoCam with Apple's drivers.

Stereo movies in EvoCam:
      Evological has a new beta of EvoCam out, links through 
evological.com -- it works better, more choices and settings.

Unibrain cameras:
   Their support (finally) told me their  "fire-i" camera settings last 
only as long as the application changing them is open.  Unibrain makes 
a Windows app that supposedly saves and reloads settings, but again the 
settings are lost when that app closes.  No other app can save settings 
and reapply them.

Apple IIDC bug:
   Several people have told me there's a problem with IIDC cameras when 
two are used at the same time -- one of them will eventually go 
magenta-blurry and quit updating.  I see this happen a lot, and can 
only get a few minutes of stereo movie recorded before one camera quits 
updating.

Apple IIDC throughput limit:
   I did find an Apple tech note saying the total throughput is about 80 
percent of the 400 bps for the single internal bus and adding another 
bus using a PCI card is the only way to increase it -- not possible for 
me with my Powerbook G3 Pismo.

   Has anyone any guidance for what settings make what sort of 
difference in throughput?  I'd appreciate any help, I don't really know 
where in the process any of the compression, shutter speed or other 
settings occur.  I can imagine that the two fire-i cameras simply run 
full bore no matter what compression is set, but I would guess the 
settings that are available using BTVPro or EvoCam (shutter speed, 
brightness, sharpness) are being made in the cameras and might change 
how much of a signal I get through the bus.
