Jason, do you get firmware loading fails on boot with the PCI device? There needs to be a delay put in the firmware download of at least 250uS after each write, but this does not solve the corruption. I have tried everything, but all of them fail to get rid of the corruption on the first frontend when the second frontend starts and then corruptions every 5 seconds or so. These only come through demux on endpoint 84 and are not caused by any other frontend operations. Trouble is, on a Nvidia motherboard I have it does not do it at all and all applications work without any troubles. This seems to suggest a USB motherboard driver issue. However, the frontend lock does make it at least work on Myth TV. I am continuing to look into it. Regards Malcolm
