Wonderful software (you already knew this, right?)
I can't believe I was using Dr Tag for almost a year!

Small problem that crops up in some of my files...
tracks that MP3Utility had cleared as error-free often show up as having having a sync error at 0:00 minutes into the tracks after I've used MP3TS to edit tags and rename the files.

The errors don't seem to be audible. But I worry that it might cause an occasional lockup in my Nomad Jukebox (which doesn't have the power to do all the error-correction that Winamp might do)

I've saved a before/after sample that I can upload to webspace if anyone has any ideas about this.

Which program reports that the files have a sync error after being tagged by Mp3/TS?

Please mail the sample files to me (I don't want the board to be accused of distributing mp3s), and I will take a look.

Thanks.

MP3Utility --> http://www.geocities.com/mp3utility/
- a popular utility among Nomad Jukebox users

MP3Utility reports that the MP3 files are okay, until I edit the tags with MP3TS (after which MP3Utility reports sync errors in the MP3 files at 0:00 minutes)

umm, let's see. I'm running winXP (maybe that's the problem) on an old P3-866, using the latest 3.01 version of MP3TS

I'll email one of the files to you. I'll send one that's still 'clean'

Some chance that this could be related to the Private/Copyright/Original flags. I had a track that acted similarly after MP3TS tagging. I changed to "Whole file" in Mass set tags/flags, applied, afterward there was no problem in MP3 Utility. But as Magnus points out in the program, this does have the potential to damage the file. More info on that, Magnus?

Or it might be nothing of the kind  :p

Tagging a file with Mp3/Tag Studio should not touch the mp3 sound data at all. Changing the flags in the file might correct an inconsistency that existed before though. My guess would be that there is some bug in the other program that reports this error. Either that there is no error at all (i.e. false alert), or that the error existed before the tagging too, but was missed then for some reason (bug) when there was no ID3v2 tag in the file.

And files can only be corrupted during the flag setting process (NOTE: Not tagging process) if they are already containing certain kinds of damages. In normal cases there should be no problems at all. But it can never hurt to keep a backup during the operation anyway of course.

Interesting idea, Disposable Hero. You might be on to something there.

I didn't think to mention it before, but I routinely set the Private/Copyright/Original flags to 'No' (Header only) when retagging MP3s.

No, you did not mention this before, but things sure would have been easier if you would have. ;)

I just analyzed the files you sent me, and just as you say, the original flag of the first frame has been modified, and that is why the other program thinks that it is not synced with the next frame.

This will in no way affect the playback of the song, and nothing else either. To be completely "correct" when changing the flags you should change them in all the frames in the file though (like Disposable Hero said above), but since this takes more time, and since most programs that even care about these flags only look in the first frame anyway, I added the option to only change them in the first frame.

The flags have nothing to do with the tagging, they are included in the mp3 frame headers, and a normal tagging won't touch them. It is only when you explicitly change them in the mass set tool (or browse tool) that they are edited.

If you have no "real reason" to change them, you probably just should leave them as they are. But as I said, it does not really matter for any other reason than to shut up nitpicking mp3 analysis programs. :)

Well that was certainly the problem. I actually didn't realize that setting flags was separate from editing tags, and therefore didn't think to mention it. My bad. Anyways, problem solved. Thanks, you guys.

Now what should I do with the 2756 tracks likewise affected? Leave well enough alone, or make backups and reflag each and every frame... or switch back to vinyl?

I would just leave them alone. As mentioned earlier, it will not affect any player anyway, so it is not a problem.

Your word is my command. I shall leave them well enough alone.

(So you wouldn't even consider going back to vinyl?)
