thanks again for your very useful guide.  i have a question.  what exactly is the point of taking the AC3 audio and making it into WAV format?  i've now done the reauthoring a few times without doing this and i can't seem to see any reason for doing so.  but i was wondering if there was a specific purpose for it or doing so avoids issues in the future. 

Most DVDs have their audio track in 6 channels.  If you import that in to Audacity, it spreads out over 6 tracks in Audacity (try it some time to see exactly what I mean).  It makes it much harder to sync it up with the Rifftrax.  Converting it to WAV format smushes this down to 2 tracks.

It's not required, but I always found it much easier to sync when there are only two tracks involved.

personally, i haven't found it difficult to sync at all with 6 tracks.  audacity is actually pretty easy to use once you get the hang of it.  it takes forever whether you're doing a WAV or AC3, but i find it easier not to have to convert to WAV.

I can understand that.  I never really took the time to figure out how to sync with the six tracks.  I use the tracks visually to achieve a sync that's perfect down to two tenths of a second.  I can SEE where the movie's line is and where Disembaudio's sync line is.

I thought it would be too complicated to explain that the conversion was optional, so I just left it in there as is and will let people come to their own conclusions as they get used to reauthoring.

OK, I've just tried to make my first ever Rifftrax DVD (300) following your guide, and I'm 90% happy with the results, but I do have some problems with the audio.  When I play the disk, the audio from the original movie keeps "breaking up" every few seconds, particularly on especially loud noises (like the thunder at the beginning of the movie).  The audio is also slightly out of sync with the video--just enough that the voices don't exactly match up.  Also, the voices of the riffers are all pitched very high--they don't sound at all like their actual voices.

Could this be a result of overcompression?

I think the problems are probably with Audacity, which I confess I had some problems with.  I can already tell that it takes some practice to get things synched perfectly.  One thing I noticed was that the "Project Rate" in the lower left corner kept changing back from 48000 to the original setting.  I changed it every time I noticed, but it might not have been set at 48000 when I exported the combined file.

Comments and suggestions welcome--I guess I shouldn't expect the first time to be perfect!

FYI: You don't really need Chapter Xtractor to get the chapter stops. If you select "Chapter Information - DVDLab" in the DVD Decrypter settings, it will give you a file with chapter times.

i have been using chapter xtractor to get the stops because apparently rejig doesn't do too well with chapters.  one problem i'm having with rejig is that the movies i do reauthor will not resume on the same spot if stopped.  on any of my DVD players if i stop the reauthored DVD it will automatically go to the next chapter when i press play again.  i'm not sure if this has anything to do with using chapter xtractor or if it is just typical of rejig (which i use to rip and remux the dvd.)  i doubt if this has anything to do with it, but i always include the subtitles in the movies.

Hey guys.  I'm (eventually) going to update the top post with links and/or short tutorials on dealing with some of the trickier movies.  Help me put together the list, would ya?  Off the top of my head, I can think of:

Star Trek (2009)
Transformers 2
Casino Royale
The Dark Knight

I know there were more than those four, so help jog my memory.

Also, if someone knows how to add forced subtitles for Return of the Jedi, Red Dawn, and Dragon Wars, through Rejig, that'd be a handy guide.  I used DVD Lab so I have no clue.

Twilight had some funky audio sync issues. Although I can't remember if I added or subtracted to the audio track to get it to sync up.

Twilight was a major pain in the ass.  one that gave me problems even more than that (although seemingly not a problem with anyone else) was Next.  Titanic was also a bit of a problem likely since the audio was such a big file, it didn't mux back right. 

in my experience rejig tends to add every subtitle as "forced".  every disc I made with rejig had the entire sub track on every time i put in a disc.  i don't know if i ever added more than one subtitle track, so i don't know much about that one.

I just posted in the X-Men forum (which I'm sure people check religiously...haha), but I'm having a really weird issue with reauthoring that DVD. To save myself the time of re-explaining it, here's my post:

I just recently got into making my own RiffTrax DVDs and have run into a few problems here and there with certain DVDs (which I've heard is common). I'm having a really weird issue with my X-Men DVD (bearing in mind that it's not some goofy version of the movie; it's just the original release with solely the first flick). Every time I rip it using ReJig, the video completely skips the sequence in the beginning where Rogue puts that dude in a coma; it goes from a shot of the house, to her screaming because he's seizing, then gets into the scene with the senate hearing thing.

Any ideas? It's a weird issue that I haven't heard about...Thanks in advance for the help :-D

that could be a flaw in the disc itself.  i had a similar problem with Independence day.  i've learned to make an ISO of the original disc  using DVD shrink and mount that ISO image before using rejig to rip the ISO image instead of the disk.  i have found that this reduces problems with the discs.  i didn't have that problem with X-Men so assuming you are using the original DVD, that would be my only guess.

What's the whole "mounting" thing (besides a setup for Michael Scott's "That's what she said!")? The weird thing is that I've ripped the dvd using dvd decrypter and it all works fine. I'll rip it using DVD shrink now, but some more help would be amazing :-D

What it means is using a program like Slysoft's Virtual Clone Drive.  The program is pretty intuitive.  You create a virtual drive that is assigned whatever letter is available on your computer.  Mine uses the E: and F: drives.

Then you can mount an ISO file and it becomes a virtual disc in your drive.  Try downloading the software.  It's pretty easy to figure out.  The result is that you the computer has a virtual DVD in a virtual DVD drive that you can rip.

Kinda like this.

Also, though I barely remember it, I had the same problem, and it  was the topic of my very first post.

Thanks so much for this awesome guide!  Just did my first successful re-author (300). The first disc I burned had the riffers sounding like chipmunks but I realized that I hadn't set Audacity project rate or whatever it's called.  Once I fixed that and re-burned the disc it seems to be working fine.  The riffers are a little loud but that's fine, I don't need to hear the movie when the riffers are talking.  Going to try The Happening now.
