"Would I be correct to assume that if the audio wasn't upmixed to 5.1 for the AC3 track that home theaters would decode the DD track as 2.0 (left and right only), whereas a stereo PCM track would be passed to the ProLogic decoder and be played as 4.0 (3/1.0)?"

That is correct. The reasons I created this 5.1 track were 1) to see if I could do it , and 2) my receiver doesn't have Pro-Logic II, so I figured I'd recreate the ProLogic decoding in software, and then save it as an AC3, which my receiver could decode (plus it makes the file smaller as well.) I, and many others, were pleased with the result.

"One last question, what is more vulnerable DSI which only took a squadron of X-Wings to bring down, or DSII which took the whole rebel fleet?"

Actually, both DS's were brought down by individual ships taking out the main reactor. The number of ships outside in the actual battle doesn't change this either way. (Of course, the DS II was also hit by a SD as well. )

Both "encode" very similarly. The key difference is that "constant" keeps the same bitrate for the video across the board. This is okay for static shots without a lot of movement. For something like Star Wars, it's a terrible choice because there are alternating scenes of action and non-action. If you set thed bit-rate too low, then an explosion will not be encoded well, resulting in loss of definition or macro-blocking. If you set it too high, then static scenes, like static shots like characters standing around talking to each other eat up bandwidth that could be better used on action scenes.

Variable bitrate (otherwise known as 2nd pass, and occasionally 3rd, 4th, etc., depending on the encoder) will go through and analyze the video to determine the best bit rate for each scene. This is nice, because static scenes are given a low bit-rate, which saves it for scenes which need a higher bit-rate, like explosions. Since the bit-rate use is more efficient, you save disc space as well.

The downside: it can take a lot longer to compile the video, since you are essentially doing it at least twice, if not more. Don't expect to do much with your computer while it's doing this. (Which is a major reason why I set up two. )

"and now I'm in an even worse mood because some pissant eBay seller wants an extra $5 after I paid an received the item, their reasoning? they forgot to set the invoice postage to $15 instead of the $10 they did set and I did pay. The postage label on the package was $1.60..."

Give him negative feedback then. It's not your fault he screwed up. Be sure to include the actual amount on the postage label.

Don't believe everything Dolby Labs tells you ( ), and again, this DVD was a "Proof in Concept" - not intended as a final product. It also contains my 5.1 soundtrack created from the PCM (which a great deal of research and effort went into, as opposed to some sets that just drop a WAV file into a AC3 encoder.)

Besides, with just a few tweaks, the video would have taken up far less space, and looked immensely better as well.

"if I were in your shoes I'd want to know what the unopened limited edition box set would go for on the open market to a collector .vs. an opened one"

That's actually not a bad idea. For the price of your unopened set, you might be able to get an opened set as well as an excellent VCR. Maybe Silverwook can point you in the right direction, since I know he's in contact with a lot of collectors.

" Ah well if it's an old out-of-date version then ok; incorrect aspect ratio ("I'm crushing your head! I'm crushing your head!"), over saturated colours, looking slightly out-of-focus, too dark (black levels crushed) but apart from that the audio is good"

Well, it was anamorphic, but I didn't do any resizing beyond zooming into the picture (which resulted in a lack of detail), and I kinda eyeballed the colors. I have much better calibration tools now, and know how to use Vegas' color correction tools as well.

The audio *should* be good: It's a direct copy of the LD PCM track through the digital optical output. Can't get any better than that.

I believe I used some light sharpening, and another filter to get rid of dot crawl - neither of which will be used next time.

Another mistake I made was after IVTCing, I encoded it in Vegas with 3-2 Pulldown. What I didn't know at the time is that this de-IVTC'ed the video! Thus, the space I was supposed to save for all my soundtracks was not nearly as much as I would have wanted. (which was the ultimate goal for this "proof of concept" DVD: PCM 2.0, new AC3 5.1, and commentary track.)

If you get the full DVD, you'll notice that it's filled to the brim. I recompiled 3 times to get the video bit-rate as high as I could go. If I were to re-IVTC, and then apply PULLDOWN.EXE (a program with which I was unaware of at the time), then the video bit-rate would be much higher, resulting in fewer artifacts.

Like I said, I've learned a lot since then.
