The Magnavox MDR513 might be suitable since it has a 320GB HDD for recording. However, it's std def and doesn't have Component (RGB) input, only Composite YWR RCA or S-Video input, in addition to the normal coax. There are devices to convert a Component RGB feed to Composite or S-Video, as described here.
Click the "HDD DVDRs" link in my sig. for lots more info.
