Ok, I've tried this.  I even dumped my mythconverge DB and started
over.  still no luck with changing channels.  I turned on verbose -all
and saw that mythfrontend is outputting the following lines several time
each time I try to change the channel:

2004-03-27 15:11:55 waiting for prebuffer...
2004-03-27 15:11:55 prebuffer wait timed out..
2004-03-27 15:11:55 waiting for prebuffer...
2004-03-27 15:11:55 prebuffer wait timed out..
2004-03-27 15:11:55 waiting for prebuffer...
2004-03-27 15:11:55 prebuffer wait timed out..

There are probably about 100 iterations for each attempted channel
change. Does anyone have any further pointers on what I should check
here?

Thanks,

-Chuck
