However the UHF channels seem to loose sync rather quickly, causing the screen to scramble or roll. Has anyone else observed this problem? I'm trying to decide if its the code or my particular card. I look at the tuner status byte and it shows the tuner to be locked and the AFC to be centered, so I don't know what to blame. I have updated the ioctls to allow separate access to the U and V registers, anyone having a need send e-mail and I get the patches to you. I'm not going to commit them for awhile cause I'm still futzing with the tuner code in general. -- Steve Passe | powered by smp@csn.net | SMP FreeBSD
