Changing the configuration for channel seven from "hierarchy: NONE" to "hierarchy: AUTO" and "Guard interval: 1/8" to "Guard interval: 1/16" allows me to get standard definition channel 7, but not HD or the guide. More experimentation is necessary. I can only assume that; A) the out-of-the-box configuration on Mandriva 2006 is wrong B) the driver is smart enough to correct for mis-configuration C) some interaction of the Kworld and MSI clobbers the auto-configuration capabilities of the MSI driver. Perhaps something somewhere discovers that auto-configuration is already done (or does not need to be done) once and does not try a second time? I am just guessing here. -- Peter D.
