Ah OK - I discussed this with a friend, and he couldn't see why an exact copy couldn't be made by choosing "clone" or "copy" in k3b or similar (as I said to you, I have no DVD burning capability here so I couldn't try it..) > > So I can now copy the disk with ease.

Iso_dump reports it as "mpeg1 ^@^@ ( ) 16bit 48kHz 2Ch Not specified 0" (yes, complete with two binary characters there transcribed as ^@^@). Nor does acidrip nor anything else. Ffmpeg, for example, identifies it as "MP2". As a result what comes out is dead silence with AcidRip just not bothering to write an audio track at all and ffmpeg writing one out that translates to no sound. The solution to this video mess is two-fold: 1. To make clones of this DVD, I had to use "vobcopy -m" to mirror the files. At this point it's just a simple DVD burn away treating the extracted files as I would any data DVD. (An annoying problem with Nautilus' DVD burning tools is that empty directories -- AUDIO_TS in this case -- get ignored. I imagine that some really picky DVD players won't like that.) 2. To turn the DVD into an AVI complete with audio I used "vobcopy" (no "-m") to make a single, big VOB and then used ffmpeg on it. The key is that on the output I have to put "-acodec copy" to just copy the sound in place. When I do that, even Totem can play it! So the solution is ugly (in traditional UNIX style), but it now works and I can actually send my wedding video to my relatives and friends around the world as well as make copies for local friends and relatives. <TABLE CELLSPACING="0" CELLPADDING="0" WIDTH="100%"> <TR> <TD> -- Michael T.
