When using IfoEdit 0.94's Author New DVD function, the resulting VOB files I get (except for the last one) are 1.00GB + 1 LBA (1'073'741'824 bytes), rather than the normal 1.00GB - 1 LBA (1'073'739'776 bytes). When I try to burn the disc with Nero v5.5.8.2 (under Win2k), I get the following error:

File size is not a multiple of a logical block size (2 kB)

When I set the custom VOB size to 524287 (1.00GB - 1 LBA) and process the VOBs again with IfoEdit, I can then burn the disc without any problem (as all the Vobs now have size <= 1.00GB - 1 LBA).

From Doom9's discussion of the Sneakers DVD in his rippers comparison (http://doom9.org/dvd_ripper_comparison.htm), my guess is that Nero uses the Windows UDF parser to examine the files, so when the UDF parser fails to open the file, Nero won't accept the file.

I have only tried the Author New DVD function twice, but since the results were the same both times (using different m2v and ac3 files), it seems like it could be a bit of a bug. (That is, the result is undesirable, even if it is still a valid set of VOB files.)

Has anyone else tried the Author New DVD function? If so, do the VOB files turn out the same size as mine?

If I were to put the files into a VIDEO_TS folder and just use the UDF/ISO compilation in Nero rather than the DVD-Video compilation, would the resulting DVD play on most standalone players (assuming that everything is correct other than maybe the file sizes)?

Uuh, realy?
I didn't notice that yet. That would be too bad, cause a VOB should have a max size of 1GB - 1LBA.

So it must be a bug. I'll check that.

i've tried to author an .m2v and .mp2 using ifoedit,
and for me Nero also complains about

"File size is not a multiple of a logical block size (2 kB)"

i burned the dvd anyway, it works perfectly on dvd-roms on pcs,
but not for a standalone.

does anyone how i can get a working dvd out of ifoedit, if i have
just an .m2v and a .mp2 file ?

borchers,
Using IfoEdit 0.94, you should be able to get a working DVD by doing the following (you need enough disk space to write all the VOB files a second time):

1. Use the Author New DVD function to join the .m2v file and the audio (.ac3 in my case, but .mp2 should work identically). This gives VOB files that are too big, but that is taken care of by the next steps. (It sounds like you're already here, so just go to step 2.)

2. Set a custom VOB size (see http://forum.doom9.org/showthread.php?s=&threadid=29018) by adding or changing the following line in ifoedit.ini:

bVobSizeCustom1=524287

(bVobSizeCustom2=524287 would of course be fine as well, as long as you choose "Custom 2" instead of "Custom 1" in the next step)

3. With IfoEdit, open the VTS_01_0.ifo created in step one. Click VOB extras. Under VOB EXPERT options, set VOB size to "Custom 1". Make sure that "Correct Vob-Unit (Nav Pack) pointers in VOB-files" and "Correct original IFO files" are checked. Choose at least one of the other options (except "Rebuild PTS" and "Create Subfolders") so that you can enter a Destination directory. Click OK. Depending on which options where checked, you may need to tell it which streams and VOB-ids to keep (you probably want to keep all of them). Once it finishes writing and correcting the VOBs, load one of the .ifo files it just created and click Get VTS (if you did this after step 1, it might not be necessary, but it doesn't hurt to do it here again, just in case). You should now have a working DVD that Nero will burn and that a standalone should play.
