All things being equal, its usually best to do the initial recording in the mode that you intend to use on the final disc (i.e., record in SP if you intend to archive your recording in SP on a disc) because it enables you to do a high speed dub. Why is a high speed dub preferred? Two reasons. First, obviously, its faster. Second, a high speed dub is a pure data transfer so the original recording "data" is undisturbed during the dubbing process. A real time dub requires the original data to be re-encoded, this is true EVEN IF YOU ARE NOT CHANGING THE RECORDING MODE DURING THE DUB (i.e., an SP to SP real time dub is re-encoded). Even if you are real time dubbing from an XP source, the re-encoding will further degrade the PQ vs. recording to the HDD directly in SP, editing, and then doing a speed dub to disc (albeit this degradation is slight, and may not be readily noticeable depending on the nature of the dubbed content - high motion or contrast scenes generally suffer the most degradation upon re-encoding).
Confusion: high speed vs. normal speed (Pana. E100 or E95)
I'm new at this and somewhat confused, so please be kind!
I have read that using high speed for dubbing produces better video than using a real time mode. Is this true?
An example.... say I record a show on the HD using XP (assuming it will be the best quality possible). Now, I want to copy to RAM or DVD-R.
High speed restricts me (I assume) to making an XP copy onto disc.
What if I want to make an SP copy of the original XP (HD) recording?
I assume that I have to do this in real time.
Is there much degradation in quality?
Am I better off if the original HD recording was done in SP and then I just do a high speed dub.
My thinking is that if I record at XP on the HD and do a real time dub onto disc at SP (to use more of the disc) , I am getting good quality.
Is the high speed (SP to SP) method as good or better. It is certainly more convenient to use high speed!
WHAT ARE THE BEST OPTIONS, IN GENERAL, FOR DUBBING ON A PANA. E100 OR E95 UNIT? I AM CONFUSED!
ANY AND ALL SUGGESTIONS AND CLARIFICATIONS WOULD BE MUCH APPRECIATED!!
THANK YOU!!

Vic's absolutely correct, and I'd just like to add a third reason why HS dubbing is preferred: It allows you to add chapter markers.
Well, I think i can add a fourth reason: when you use HS dubbing usually you get a little more time per DVD. For example, in a real time dub (lets say at XP), you can only get maximum of 1 hr / DVD. If you use HS dubbing of XP material you can get more than that (around 1h03m).
Perhaps you think this is not usefull at all. Well it is: for miniDV tapes wich are actually 1h02m30s and you actually can HS dub one complete miniDV tape content, recorded in XP mode, to one DVD-R.
At least, this is true for pioneer DVR-510. But I suppose it's the same for panny recorders.
Best regards,

It is, I dub primarily in SP and get 2:07 on my discs.

If you record something that has continuous fast-changing scenes throughout its length then it will be recorded with a higher average bit rate (compared with scenes which are 'slow'). If that’s the case then you will probably find that you won’t be able to HS dub a program which has a running time of 2.07 because the file size will be bigger. That’s why the manufacturers have built a bit of slack into the machines when recording directly to a DVD (hence, SP is conservatively maxed at 2 hours).
