Altough it's not something I have first hand experience of - I have no AC3 laserdisc titles and no demodulator - but I have heard this theory repeated several times on forums for AV enthusiasts. The Phantom Menace (AC3) and Titanic (DTS) are two movies in particular that sping to mind.

That said, it would probably be easy enough to prove - a simple measurement of average vs. peak levels should show if the laserdisc track has a higher dynamic range.

The video corruption is possibly due to you capturing in a format or resolution that your capture device doesn't like. What settings are you using?

To get audio you will normally need a cable with 2 RCA/phono plugs on one end and a stereo jack on the other (I think you call them "miniplugs" in the states?) The RCA plugs go into the red & white sockets on your camera, the jack goes into the line-in (normally blue) on your PC's sound card.

Panorama() - an AviSynth function for converting 4:3 into 16:9

Things are not so clear cut if you're making an Xvid AVI file, because there is such a variety of devices that they can be played back on.

I would not recommend adding borders, for an Xivd file it's a waste of bitrate. Make it with a smaller horizontal resolution instead.
Similarly, I don't know if you would really want to crop - maybe that will happen when it's played back on a widescreen display.

The way I would do it it to modify the final line in the function:
return clp.lanczos4resize(720,ht)
replacing 720, ht with your desired width and height values. This assumes that if the source is interlaced that you have de-interlaced before Panorama.

Obviously would you need to experiment to your own requirements, but for a start you could try a resolution of 640x384 (1.66:1) with strength 3.

Yes that's right - you need to rename huffyuv_ccesp-patch_0.2.5.dll to huffyuv.dll. Once it's renamed, just right-click on the .inf file and select install.
When it's installed, you can delete both the files.

The package at Doom9 includes the source code (which is not required to install) and unfortunately is a little confusing to wok out how to install!

In this case, normalization is not required. Just make a note of the dialnorm value in the original PAL bitstream, and use the same value when re-encoding the slowed-down WAVs back to AC3.

You could encode the video to 25fps and use DGPulldown to apply the relevant pulldown flags, and mux with the unchanged PAL audio. However I think you'd be better off converting the audio.

First you need to check if the PAL audio is a straight speed up, or a pitch-corrected version. Listen to a portion of the NTSC audio, then the PAL, and if the PAL sounds higher pitched then the conversion is a simple process.

(You should also check that the video ripped from the PAL DVD has the same number of frames as your IVTCed HD conversion.)

BeSweet is fine for the rate conversion, but the encoder BeSweet uses (ac3enc) is not as good as commercial software. Therefore, I'd output 6 channels from BeSweet and feed them into a commercial AC-3 encoder if you have access to one.

Buy it through Paypal.

When you receive it, complain to your credit card company that the seller has sold you a bootleg DVD, and you want a refund.

With any luck your credit card company will recharge paypal, and the scum will not only have to refund you, but may also have to pay a chargeback fee as well.

In the meantime, you've ripped the DVDs and put them on a torrent site for everyone to download for free.
