Sony DVDirect
Seems to work ok with single layer DVDs but dual layer gives this error:

Failed to open disc
Using direct disc access mode
Calculated BUP offset for VTS #1 does not match one in IFO header.
IFO file for VTS #1 is corrupt, VOB file must be scanned. This may take very long time, please be patient.
Title #1 (3:50:41) was skipped due to navigation error
Title #2 (3:50:41) was skipped due to navigation error

It is especially sensitive to dvd burns that go to the end of the media and cutoff.
This happens with overnight burns often.
I am forced to transfer media over 2 single sided disks when over 2 hours in length.
It kinda sucks. LOL I sure hope there is an answer.

Did I post this in the wrong spot? Is there some other details I can give? Is this a recording device that you are not interested in supporting or are you investigating? Thanks for reading.

While it probably won't help with this, have you tried it with version 1.8.3, which was released last week?

Thanks for the reply.
I have not, but the issue is intermittent so it may be recorder related.
I was able to extract 1:47:00 from the disk using mkvmerge. (Loading the VOB)
It resulted in a video that abruptly stops within media player classic.
Windows Media Player seems to load the entire movie but seek does not work.
I think my DVDirect is having issues finalizing the 2nd layer of the disk.
Maybe it is a bug in the firmware. I am checking for updates.
