OK, I think I'm part way there. I've downloaded and installed a kernel source rpm from Fedora's download site. In the BUILD/kernel-2.6.11/linux-2.6.11/drivers/media/dvb/ directory are various files for what I think I'm needing for the Nebula card (bt8xx, bt878, mt352). Am I correct in thinking that these files need to be replaced with the updated ones from the CVS here at linuxtv then recompile this as a new kernel to get the card working? If so, which files need to be replaced? Thanks, -- Best regards, Derek
