I thought that Echo Fire was discontinued a while back – soon after AE supported firewire out on its own.
Anyways, look for your AE Prefs file and open it up with a plain text editor (best to make a backup with a Save as routine before venturing further).
Then scroll down to the bottom of the document and look for
[“Win32 Video Preview Pref Section”]
“All Window Updates” = 00
“Device” = 0000000000000000000000000000000000000000
“Device Display Mode” = “1”
“Disable OHCI Preview” = 00
“Disable QT Preview” = 00
“Including While Rendering Movies” = 00
“Mirror on Desktop During Playbacks” = 00
“RAM Previews” = 00
“Scale to fit video monitor” = 00
“Scaling Quality” = “1”
“Video Monitor Aspect Ratio” = “1”
Off course you’re on a Mac, so it won’t say Win32 there but look for Firewire Preview or perhaps IEEE1394 Preview. Set it to 00 ( 2 zeroes).
The other two crucial items to look at are Mirror On Desktop …
AND
“Device” = 000 … (that’s 40 zeroes in there)
Ensure that your prefs are set to those values. Save the file – ensure that it is plain text format. Recite your favorite prayer and restart AE.
Good Luck
