Ok here is what you do, get rid of redhat and download Mandrake 9.1
It worked for me cause I have a Ati Radeon 7500 All-In-Wonder Pro. It is a combination of their all in wonder cards and the 7500 graphics chips. I used both redhats 7500 drivers, and the all in wonder and got nothing to work right. Now i use mandrake and have TV and everything. AWSOME!
