Hi, Sorry for the late reply on the firmware question. I don't have high hopes for the new driver "making it all better". Since the red-screen, if it happens, happens at boot. A power cycle is needed to clear it. This really indicates the cx18 driver is racing with the CX23418 hardware or with the cx18 driver itself somehow. Nothing has changed with the driver init sequence in a long time. > Thanks for the help again... If I find time to change the driver to load the firmware early, I'll email that I need a patch tested. Hopefully sometime in October.... Regards, Andy _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
