I am aware that sequential writes are always going to be much faster than random read/writes but I still do not understand how there is a problem here.. > What I personally see is on AMD XP mainboards, you > sometimes can max out the system bus.

Why does the pchdtv send a stream that is more than twice the bandwidth of ATSC? Where are you getting these numbers from? I have to assume you mean megabit.. But it seems like you are mixing and matching units here.. Because even a 150 megabit stream shouldn't slam a pci bus. _______________________________________________ mythtv-dev mailing list [EMAIL PROTECTED] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-dev
