I would like to know which will produce a better picture when dubbing as I've heard several different stories when the machine encodes and re-encodes.

I have a 2 hour 10 minutes movie on my HDD taken from a Laserdisc. Which is the best way to dub.

1. Take the contents that is on the HDD and dub it in LP or FR directly?

2. Make a Playlist first and then dub it in LP or FP?

I guess I am asking is that if I go direct from the machine... does it only encode it once and/or going from a Playlist... does that make it encode it twice... or is there ANY differnces at all?

What speed did you originally record the movie in? If you recorded in SP mode, you should be able to High Speed dub it without having to re-encode down to a different record mode.

Anything besides "high-speed" mode on the Panasonic will resample (and thus degrade) the video in the process of getting it from the HD and on to a DVD-R.

But why go LP/FR? I think a 2 Hrs 10 Min. program should just fit on a single DVD-R at SP -- if there is NOT the overhead of using playlists and multiple titles to get it on there.

I would turn on High-speed compatibility, re-acquire the thing on the HD at SP, and high-speed dub it to DVD-R. For a movie I particularly loved, I'd go XP and splurge $2 on the extra blank disc. I _know_ that the Panasonic will fit 65 minutes on a DVD-R at XP...

So if I record the 2:10 Laserdisc onto the HDD in SP... then I should be able the use High-Speed dub and that will not re-encode the DVD?

Usually I use XP to the HDD for the best quality from the original source. Isn't SP a lower quality? Then I wonder what way will look best...

Going to the HDD in SP (Lower quality) and then dubbing in High-Speed with no re-encode... or

Going to the HDD in XP (Higher quality) and then dubbing in SP/FR which then re-encodes the DVD?

TonyRz... 2:10 is too long for SP... or so it says.

A high-speed dub never re-encodes the video that's on the HDD. Naturally, there will be at least one re-encoding taking place in this process: when you "record" the LD content to the HDD in the first place.

Yes, SP is lower quality than XP.

Well, unless blank DVD-Rs cost you $20 or something, or your time has no

value at all, I'd recommend doing that which takes the least time and preserves the quality to the best of your hardware's ability.

I don't know what to say about that. I've repeatedly fit 1:12 on a single disc at XP. I'm pretty sure 2:06 will fit at SP. Can you chop the cresits?

I am just worried which will produce the best picture quality. Blank DVD's and time are not a factor. Quality of the picture is the most important.

Going to the HDD in SP (Lower quality) and then dubbing in High-Speed with no re-encode... or

Going to the HDD in XP (Higher quality) and then dubbing in SP/FR which then re-encodes the DVD?

I am transfering my LD Star Wars to DVD and then storing the LD stuff away. That is why it has to be the best possible it can be.

So what do you think then would be the best in the above 2 examples???

Create a dubbing list and see if it will fit. Depending on what brand dvd-r you use, the Panasonic may be able to put 2:10 or even 2:15...

I have 3 episodes of Lost recorded in SP mode on a single disc-minus commercials...A one hour show is around 42 minutes with ads deleted, two comes to 1:30...
