I spoke too soon.  I tried a couple of other things and found that the
problem was with using the "EnableAGPDMA" option.  Once I took that out,
xxmc works fine in xine.  Now, I have one more question for Ken (or
anyone that has an answer).  How did you go about getting the proper
mode settings worked out for the 720x480under mode?  I really would like
to get the 720x480over mode to work since I will be using this to watch
TV with mythtv.  Any help you can give me or any website you can point
me to would be greatly appreciated.
Thanks,
Joel
