I am trying to weigh up whether to buy an Archos 404 with a DVR stand, or an Archos AV 500. The primary use for the device will be to record from TV and also to use it as a playback device on the television. I was just wondering whether there would be a difference in quality between the two units? The Archos AV 500 seems to offer an all-in-one solution, whereas the 404 would be standalone and would use the DVR stand to record as a passthrough device. Would this affect the quality at all? I can get about the same deal on both and am trying to decide whether it would be better to get the 404 since it is two components (making it cheaper to replace if one part breaks) or whether I should just get the AV 500 and keep things a little simpler.

Thanks for any help!
