I'd like to fix the startup animation, but I don't have a network card. This means that I cannot follow the following step:

3. Enter the following address into a browser, where the x's are your TiVo's IP: xxx.xxx.xxx.xxx/mfs/Resource/VideoClip
Is there any other way to figure out the line number? If not, can I simply use 1507 or could that cause problems if the number doesn't match? (I'm using the 1.62 image.)
