Copying to a higher bitrate would not improve the Picture Quality over the ORIGINAL. I realize that's not what you're asking. LP->LP is likely to degrade the picture quality slightly, less so with LP->SP (or better). This is why we tend to recommend against re-encoding, because PQ degradation is unavoidable. This is a similar question to what's the best bitrate to record VHS at, even though VHS quality is low, it still pays to use a high bitrate. Same with your LP original content. But the difference may not be worth worrying about, that's a subjective call, in the eye of the beholder, you'll have to make that decision yourself. Just try it both (or all three) ways and make your decision based on what you see when you play it back (and of course the other factors like being able to fit 4 programs on a disc).

Copying between HQ,SP,LP,EP, etc...
If I have a 1 hour home movie recorded in LP(4 hour mode), and I copy it using a DVD Recorder (not lossless), would using HQ or SP really be any better than recording to LP(4 hour) just like the source?
The source disc obviously has no better resolution than the copy. However, with all of the D/A and A/D re sampling, would every next generation copy show picture quality degredation similar to comparing recording a TV in HQ versus LP?
If I was copying DVDs, I'm sure going form HQ->LP would be worse, but would going LP->HQ really look better than going LP->LP ?
You can see what I am getting at... Four 1-hr movies combined to one disc would be nice if the quality was good.

One way to look at this is this way: If you save a picture after making adjustments, is it going to make a difference if you adjust the quality to 75%, 50%, or 25%? You may not notice the change at a quick glance, but when you zoom in or look closer, you start to notice, "hey, this doesn't look as good".
