Re: HDTV stuttering

Actually, if your formula is correct, Pete's numbers are right. The clock on
my card is 275 MHz...only gets to 550 after you double for DDR:

So, I should expect the HDTV to continue to stutter if I use this card?

Also, where did the 10GB/s min bandwidth number come from?

Thanks.
