After having just purchased a panasonic dvd recorder as opposed to having previously just tested one I started doing some tests on the XP and SP modes recording off satellite. My conclusion after multiple viewings is that the SP mode is virtually identical to the XP one. Meaning it's just as high quality with only minute differences. I did this using the rca inputs because svideo produces weird vertical discolored streaks for some unknown reason. The only difference between rca and svideo besides these horrible streaks is svideo produces a very slightly brighter picture. Surprisingly it wasn't even a little clearer which is what I usually expect from svideo. If you're using the svideo to record off of satellite. Stop. If you don't already know this switch to rca because it will produce a better picture hands down. Better than the sony imo. Don't ask me why. What I am puzzled by is that when I use the svideo to record from my vcr there are no vertical streaks in the picture. Could this be because it's from an analog source unlike recording from satellite? Anyone out there with a better tv than mine tell me if they see any difference between the two modes on the panasonic?

I do agree that XP mode is very close to SP, though I was able to notice perceptible differences.

As with all video work - the quality of the output is directly related to the input (crap in / crap out) - meaning that you will see little difference on using SP (Avg 4 Mbit/sec) or XP (avg 8 Mbit/Sec) on a sat recording because it is of relatively low quality in the first place (compressed) - yes it may help 'preseve' the quality but a 'clean' picture will always compress better then a 'grainy' picture due the nature of compression.
On a similiar theme, I have recorder VHS on an LP (Avg 2 Mbit/Sec) setting and this is not noticebly different to SP for example ...
However, on recording from a DV camcorder, expecially with lots of motion (football match for example) then XP is a LOT better then SP and really keeps the detail and sharpness.
Just some thoughts .... -
I currently have the dmr-50 but have tested the dmr-e80 in the past and saw the exact same thing but because I didn't record too much stuff off of satellite when I tested that unit out I kind of put it out of my mind. I also heard other ppl discuss the same problem in another forum sometime last year but didn't understand it at the time. Now I know what they're talking about. This is not coincidence.

Is it a HUGHES receiver? Those things suck great big <insert any expletive here> ... never seen one WITHOUT mess in the output.

Yes it is a Hughes. Let me also point out that I also received a homemade dvd someone made for me using their panasonic dvd recorder and I saw the same "bars/streaks" on the picture of that as well.
However I believe that recording was made on a panasonic e30 and from a vhs source and not satellite. Btw I don't see the problem simply from having the svideo plugged into my machine. It's only present after the recording. That has to be the fault of the recorder
