  • Internal Muxer Error Victim

    Hi folks,
    I'm totally frustrated and I've read and tried everything (so far).
    Anyway I've got a 1.8 gig project with no menus that has burned fine before. I made some small changes and recompressed my mpeg2s and now I get the Internal muxer error when it is Muxing VTS_01_1.VOBk.
    The strange thing is that I divide the project in half and I can successfully burn the first half or the second half, just not the total project. So my assets are OK. This would seem to indicate that I'm encoding too high but when I set all of the encoding preference to their lowest possible levels I still get the muxing error.
    I've tried reinstalling DVDSP, throwing out the PAR files, I have no chapters set, etc.
    Here's my Log

    What's on V1? Do you have more than one asset there? Any breaks? How did you encode the MPEG-2 files? How was the audio compressed? Have you done this before? If so, is there anything you are doing different? Can you play back the MPEG-2 in either QT Pro (you need to have the playback component) or if you have VLC or MPEG Streamclip. Does it playback in the simulator?

      First, try substituting AC3 audio instead of AIFF, if you are using AIFF. If this solves the problem, fine. If you are already using AC3, you may need to recompress at a lower encode rate (and possibly CBR).

        Thanks for the responses.
        I'm making edit test discs to try and output the best looking footage I can so they are very simple. It's a 38 minute film.
        V1 is 10 different segments all compressed at DVD 90 minute Best Quality setting. I have done this before and I'll tell you what's different in a minute. But first, I compressed all the segments with the same two choices MPEG-2s and AC3 Dolby. I've taken these files placed them in DVDSP on their respective audio and video timelines in order. I've deleted the menu 1 and made track one first play. I've not changed my preferences from when it worked before until now that it is not working. Both working and non working projects are 1.8G.

        And as I said before when I divide the 10 segments into two five segment projects I don't have a problem with the muxing.
        What is different is the Final Cut files before I compressed them. I made edits and am experimenting with reimporting and changing formats. None of the files have changed significantly in size. I've done this before and never had a muxing problem.
        I find it hard to believe it's a file size issue. What is CBR?
        Thanks!

          In addition

          The MPEGS are 6.2mbps two pass. Yes, it plays in the simulator. No, I don't have Quick Time Pro.
          Here was a test I just did where I took the DVDSP project that muxes and replaced everything with the changed files that were recompressed. I was double checking that no preferences had been changed but again it stops muxing at about 53%.
          Here's the simulator log

          I don't know if any of those register changes might mean anything.

            It's a 38 minute film...
            At that length there's no need for VBR (2-pass) if you just do a 6-7 Mbps CBR
            (Constant Bit Rate) encode. 38 minutes is so small it shouldn't be a problem...
            I find it hard to believe it's a file size issue.
            I don't think anyone suggested it was ;-)
            What is CBR?
            Constant Bit Rate - the encoder create a bitstream that more or less hovers around the encode rate you give it (like 6.0 Mbps) VBR has a chance to skew up and down, and can occasionally throw a bitrate spike that can cause problems (which may be what's happening to your mux).

                BTW, if you have FCP you have QuickTime Pro, the key is included. I highly recommend having VLC too. VLC really pushes the envelope for playback with all sorts of problematic video files. http://www.videolan.org/vlc/

                Make sure you add MPEG Streamclip to your arsenal too, along with the MPEG-2 Playback Component from Apple.

                  Further help please!

                  So the CBR at both 7mbps and 6mbps wouldn't mux. I guess I'll try recompressing everything. I've run out of ideas.
                  All other suggestions are welcome.

                    and you used Dolby Digital AC3 audio? what error message did you get?

                      I've tried recompressing. I'm definitely using AC3 dolby and I'm still getting the same error messages.

                        Total stab in the dark here.

                        I was getting burning errors on my Dual 2 GHz G5 not too long ago.

                        My burner was in the process of dying.

                        I replaced it with a dual-layer burner for $35.

                        I don't remember if I was getting the same types of errors, but if your computer is as old as mine, and if you do your fair share of burning, it could just be that it's tired and needs a dirt nap.

                        But again, just a huge guess. Sorry if I'm not being helpful.

                          Another question

                          That's actually a possibility as my DVD burner is showing other signs of age. Just out of curiosity though, did you specifically have muxing errors. That seems like a computer function prior to the actual burning.
                          Plus I'm still able to burn an earlier iteration of the same project.
                          I'm going to replace the DVD burner though, this is an oddball occurrence.
                          Thanks!

                            I BELIEVE I was getting these errors before my last change in DVD drives took place on my G5. It's hard to remember but yeah, the drive started acting funky, was producing errors and failing to burn so I replaced it. In fact the replacement drive has been having some issues for some time and I don't use it to burn anymore. I bought an external LaCie FW and do all my burning there.

                              I really wish I could remember, Tom. It seems like so very long ago.

                              All I remember is that it kept kicking out disks without burning them and giving me some sort of error message.

                              It started out every 5 or so disks would be like that. I thought at first it was bad media. I switched brands, and it didn't get any better. Slowly over the course of about a month the frequency of the errors increased until I couldn't get any disks to burn at all.

                              Replacing the drive solved the problem. Many of the rejected disks were still useable. I've burned onto several of them in recent weeks.

                              Plus, I'm tickled pink at having the dual layer capability. It makes archiving small-ish projects much easier.

                              If I wake up with the eureka moment of remembering the error, I'll be sure to post.

                              Good luck!
