I have a Hitachi RP tv that has internal de-interlacing but has no component sockets. Some Toshiba RP's have component sockets but didn't used to have any form of progressive scan. I think this has changed (you'll need a more knowledgable expert than me) but again its only internal so wont take an extranal prog-scan signal.
Anyone else know any more.
Hopefully now that PAL-prog has been ratified there will be some TV's coming out.
