103 1. There are two chip modes - accessible by reopening the fd
104 2. The video chip knows the aspect ratio purely from the incoming MPEG
105 3. MODE A is for 4:3 TVs, MODE B is for 16:9 TVs
107 To switch to MODE A, set the aspect ioctl to 4:3 and reopen the FD.
108 To switch to MODE B, set the aspect ioctl to 16:9 and reopen the FD.
