i have a hvr 4000 too, and was just about started searching online looking for the best way to capture from a vhs to my pc. by the looks of things i'm gonna have to install my old pvr-250 if i want something decent, as the hvr series appears to be made with digital tv a priority. i was reading http://forum.videohelp.com/threads/3...capture-device but didn't find anything useful as of yet.
i was also thinking it might be better to get some kind of vhs->pc device, whereby you would connect some sort of usb connector directly to your pc and the other end should connect to an electronic box which connects directly to your vhs box's scart output. i don't know if such a device actually exists, but it's surely better than having to put up with a limit resolution via a hvr 4000...?
