You are correct that LP will give you more recording time on a selected tape. I personally have chosen not to do this as I had experiences many years ago with mosiac noise. While it did not happen everytime I could not afford it happen at all.

Research I had done at that time, led me to conclude that LP can be a "possible" reason for mosiac noise. Since tape is relatively inexpensive I would recommend us SP only.

LP should not effect the quality, since the end result are 1's and 0's.

I do not know the camera, but I would not recommend this as it will reduce the data integrity, and with MPEG-2 streams gltiches can cause much more noticable issues than with DV streams. One glitch in the stream can affect everything up to the next key frame.

You are dramatically increasing the risk of dropouts. It will not affect image quality, you're just more likely to not get any image.
LP playback is typically only likely to work in the device that recorded it. That should be clue enough to avoid it like the plague.
One of my biggest complainst about HDV is it makes no provision for recording in DVCAM format. That reduces recording time but increases reliability.

This is spot on. While a dropped frame in SD is not such a big deal, a dropout in HD will result in about 15 frames being lost. That's hard to cover up (unless you can cut away to B roll at the drop). And if you are recording something like a concert and doing the audio recording with the camera, you're screwed. (I had a dropout taping my last concert job on SP, fortunately it happended between numbers (I also was recording audio separately).

Dropped Frames and Dropouts are different. Dropouts are at the bit level and usually corrected by the error-correction firmware in the camera or deck. Dropped Frames occur when there are so many dropouts as to overwhelm the error-correction, or if you hit enough bad tape to lose a substantial part of the frame.

But to the OP - I am not aware of any HDV camera that will record in LP.
