Default Re: Bug w/ TV output on 8400 GS

I am having similar issues with the same card, with previous drivers and cards this worked perfectly. I know specifically a 7600GT worked with the component out with 480i, and the FX 6200 worked with this as well (all w/the same TV). I'm getting this silly error:

It seems to be associated with mode validations. I tried using all the "ignore" options to make it less picky (this TV definitely supports 480i or at least what previous nvidia drivers thought that were putting out with 480i). I'm googling around and a lot of people have this issue. What has changed between drivers that the mode validation isn't working. I tried downgrading drivers but it won't work with recent kernel revisions (so this requires a downgrade of Linux kernels and Xorg server versions). What's the deal with this?
