Exactly what i was gonna say. For such model a DL dvd is “good enough”. HD in this case is totally pointless as the image wont be reproduced pixel to pixel. On 20" screen you dont need HD anyway. Look closer to the screen and all you can see is noise, not pixellation(like in case of cheap digital cameras). Putting in better performing drive is, in respect to the price tag in pounds, like using a tank engine on a fiat. Cheers.
