I use a Mac G4 (PPC) with OS X 10.4.11.
I have iTubeGrabber 1.0.3. It is said to be for OS X 10.5 or 10.6, but in fact works very well in 10.4.11. Unfortunately I have somehow lost the file of instructions. Can anyone help me obtain the instructions? The developer of iTubeGrabber has discontinued developing it and cannot be contacted, it seems.
In particular, the search facility works very well, but I cannot remember or work out how to enter a URL for a YouTube video if one already knows the URL.
I should be very grateful for any help; iTubegrabber is so good an application that I should really like to go on using it.
