Hi, As a follow-up, I believe I found the source of my problem. I tracked down the problem to the kernel (top reported 100% wait time). Eventually I discovered that disabling APIC (by appending "noapic" to the kernel loader) would cause MythTV to start working.
FYI my motherboard is an NVidia 2 based chipset: MB MSI|K7N2GM2-LSR. nathan On Mar 31, 2005 1:32 AM, Nathan Cournia <[EMAIL PROTECTED]> wrote: > Hi Guys, > > I just started playing around with MythTV.
