For now, you can get video using the 4.9/4.91 release by adding your camera using the JPEG image via URL profile and the following syntax:
http://HOST:PORT/pda.cgi?user=USERNAME&password=PASSWORD&page=image&cam=1
Replace all of the words in CAPS with your own values.
Again, we're very sorry and hope to have the fix released as soon as Apple reopens for business in a week or two.
