The following script works with EyeTV 2.2.1 to speak the signal strength every 5 seconds. I'm posting this because the script I posted a few weeks ago was broken by the new release.
repeat
tell application "System Events"
if UI elements enabled then
tell process "EyeTV"
-- make sure everything between "tell" and ""EyeTV Preferences"" is
-- on one line when you copy and paste
tell progress indicator 1 of UI element 1 of group 1 of tab group 1 of UI element 1 of UI element 4 of UI element 6 of window "EyeTV Preferences"
set mySignal to get value
set mySignal to mySignal * 100
set mySignalInt to mySignal as integer
end tell
end tell
else
display alert "Enable GUI scripting in the AppleScript Utility"
end if
end tell
say mySignalInt
delay 5
end repeat
