It is against all odds, Oppo claims that 981HD does not have composite output but HDMI only, but in Sweden it is sold with composite output. Also either EU or US version, non of them supports 576i. Other, non Farouja models support 576i, but I am not sure if it also stands for the other manufacturers. It means you can buy an expensive Farouja based DVD, get it home, connect to your old type TV set and find that it does not work. It is an issue.
P.S. there is also a difference between Oppo and Denon, Oppo uses Farouja FLI2310 latest model of the chip which suffers from macroblocking. Denon DVD-1930 and DVD-1940 use Farouja FLI2301, the old version of the chip which does not suffer from macroblocking, but deinterlaceing is some inferior.
