Hi, I'm new to the ivtv-devel mailinglist, mainly because I know nothing about ivtv ;)
Anyways, I'm having a problem getting the module loaded. It was working fine for the past few months, but it quit working after I installed some RPMs for MythTV. These were RPMs put together by Terry Barnaby of the Unichrome project and were designed to enable hardware MPEG2 decoding for Epia users in MythTV. The list of rpms is here: http://www.kingcot.eclipse.co.uk/unichrome/mythtv I don't know how any of these rpms could have affected ivtv, but that is the only thing I changed. As to the symptoms, whenever I try to access /dev/video0, I get the following message: /dev/video0: No such device I will post the dmesg information, and I hope that provides some answers. My gut tells me that it has something to do with the modprobe page allocation failure, but I don't know. I have tried rebooting, unloading/reloading the module, and rm/mknod /dev/video0 and nothing has worked. Any help would be greatly appreciated.
