Hello,
I recently began burning my authored DVDs on a new computer using Nero Express and have found that these do not play on my DVD player, as I get an "unknown disc" on the display. However, the DVDs do play on the computer using VLC Media Player. I used to burn these using the same Nero Express version on another older computer and never had this issue before. Exactly the same authoring and burning software, just different hardware.
I thought it could be that the disc was being burned as a multi-session disc, that had not been properly finalized, but it seems like Nero does not have this option for video DVD burning, only for data DVD.
As a test, I took one of those burned DVDs that do not play on the DVD player, loaded it up into TMPGEnc Authoring Works into the older computer and proceeded to re-author the DVD. Because the files were already in DVD format, TMPGEnc used "Smart Rendering", which means that no re-encoding took place. The original DVD did not have a menu and so I did not create a menu for this other DVD. In theory, the two disks should be identical, right? However, when I look at the files on both discs I notice that the last file, VTS_01_05.VOB are slightly different in size and this re-authored DVD does play fine on my DVD player:
Original that does not play on DVD player:
Attachment 19325
Re-Authored that does play on DVD player:
Attachment 19326
Could this slight difference in the file size be causing the issue? If so, what could be causing the difference in file sizes? If not, what could be wrong with the burned DVDs on the new computer?
Thank you in advance for any help provided.
