Info Wanted: 1984 VHS Hi-Fi Sound – A better source for the ’77 stereo mix?
Time

As far as I know the current audio recording of the original 1977 Dolby Stereo sound mix for Star Wars was preserved by Belbucus using the analogue track on a laserdisc. Correct.
Would I be right in thinking that ... the Hi-Fi sound on VHS tapes ... is actually better quality than laserdisc’s analogue sound?
Don't know - opinion seems to be divided on this one:

(1) LD analog sound, at 75 dB s/n, is comparable to broadcast FM radio and superior to 35mm mag/optical film tracks and VHS Hi-Fi ...
(2) The audio might be considered subjectively little worse than VHS Hi-Fi.

It's also unclear whether CX noise reduction is considered in the above statements. I'm sure Belbucus would know, I'll page him to this thread...If so, would using the 1984 CBS/Fox VHS or Beta tapes provide a superior source for preserving the original theatrical audio mix?
If (2) is true, then perhaps, but any improvement (and the number of people who could actually tell the difference) would so minor that such a project would have little value.

***//BUILDING EMPIRE\\: PAL & NTSC DVD - NEW EDITION NOW ONLINE! ***

4.7GB in metric units is 4,700,000,000 bytes - roughly the size of a single layer DVDR.

Most software reports size in binary units, so 4,700,000,000 bytes is about 4.38GiB (but the "i" is usually omitted). I think that the Spleen's 4.21GiB is more likely to be correct. If I remember I will check my disc, I think it came direct from Jambe.

Color Grading/Correcting
Time
There are dozens of good grain reduction filters for AviSynth. You will find lots of information at Doom9.org, but it might seem a little daunting at first.

My current favourite is MVDegrain2 (as discussed in this thread).

Colour saturation is easily adjusted by the internal filter Tweak(). If you want an easy to use GUI, I recommend AvsP.

List of stuff to download:
AviSynth (obviously)
DGMPGDec package (for reading MPEG-2 video into AviSynth)
MVTools (contains the above mentioned grain filter)
AvsP (for previewing scripts and adjusting parameters)

Color Grading/Correcting

Looking at the images above - yes the old release is grainy and washed out, but it does seem to contain more detail than the new release (look at the branches agasint the sky).

I don't know whether that's because the new release has an increased contrast which has "blown out" the sky, or whether it's been smoothed to reduce grain. (Or if it's something to do with resizing the screenshots.)

If the screenshots are representative, then best results might be obtained by running the old video through an AviSynth script with degrain filter and colour saturation boost.

Problem is, Virtual Dub can't read M2v or MPG files, no?
Correct, VirtualDub cannot read MPEG-2 files. However, as ADigitalMan says, VirtualDubMod can. You can also use VirtualDub-MPEG2 which is a bit more up-to-date than VDubMod.

DVD Lab Pro 2 - Out Of Memory error with compiling
Time
To me, "out of memory" most likely indicates a bug in the program. Most software, when running low on RAM, will use virtual memory on the hard drive so they don't run out of memory.

Make sure you are using the latest version. It might be a bug that has been fixed.

If it still occurs, contact their technical support.

If they are no help, try simplifying your DVD structure to identify where it's falling down - for example, if each menu screen has audio, try a project with silent menus.

Or try a different authoring package. (I've used the free version of MuxMan and found it to be pretty solid, but it's only really designed to do simple projects. I don't know how the pay "professional" version compares.)

So, I want to make a hybrid...
Time
Quick process:

Use PgcDemux to demux the video and audio from the Dr M disc, and the chapter points (celltimes.txt) from the EditDroid disc. (You can try demuxing the EditDroid isolated score but I doubt it will sync up to the Dr M video.)

Now use Muxman to remux video and audio with the new chapter points.

Then use Vobblanker on the EditDroid disc to replace the main title Pgc with the one you've just created above.

That's basically all there is to it. You should be able to find tutorials at doom9.org or videohelp.com, or you could teach yourself by trial and error. Give it a go and post back if you get stuck.
