It's not a digital copy, but I've been using a
Panasonic DMR-E80H DVD recorder. If I want to edit out commercials I 'burn' to the E80 hard drive (and then edit them out), otherwise I go straight to DVD. I only have a 27" TV , but the recorded discs come out (IMHO) at 95%-99% of original quality. No fussing with PCs, editing software, etc. Note: The newer model is a DMR-E85H, which has a few more features than my old DMR-E80H.
I chose this Panasonic from among other set-top DVD recorders because it featured "flexible recording" mode... which means I can put a 2hr 15min movie onto a single DVD disc and it will use the entire disc and make it as best quality as it can. Other DVD recorders are limited to standard SP, LP, EP (2hr, 4hr, 6hr) recording modes, thus for your 2hr 15min movie you're stuck recording at LP mode (4hr) with resultant poorer quality and wasted disc space.
I used
this forum for a resource when deciding on PC -vs- standalone DVD recorder, as well as for hunting a DVD recorder.
I'm very, very happy with my choice of a set-top recorder compared to a PC-based solution - it's soooo easy just to start the DVR playing and push a button or two on the DVD recorder and walk away and let it "do its thing". After the disc burn you then do any titling you want via the E80 remote (somewhat clumsy, but not too bad), then "finalize" the disc so that it will play in another DVD player.
