Re: Strange multisession DVD+R behaviour after closing the disc



READ TRACK INFORMATION[#2]:
Track State:           invisible
Track Start Address:   2055392*2KB
Free Blocks:           0*2KB
Track Size:            4294967232*2KB

Note essentially bogus value in the last Track Size.

Where can I find information/documentation to interpret the output of dvd+rw-mediainfo?

Well, in MMC specifications, but in vast majority of cases common sense is more than sufficient. In this case for example how large is 4294967232*2KB? It's like 8TB, right? It's obviously bogus...

Out of pure curiosity, Windows recognizes the size of the disk as 4205248512 bytes,

Examine track sizes in your dvd+rw-mediainfo output and use common sense. Windows obviously dismissed second session and landed on first track.

while Nero Burning Rom 6.6 shows, in the disk info dialogue window, this information:

Session 01 (8025 MB)   <-- (strange, because the disc is a single layer DVD+R)

So it shows some insane values too... Something is crazy, but does it really matter what *exactly* is? It might turn out that dvd+rw-mediainfo erroneously expanded sign bit somewhere, which made the value appear more insane that it really is, but it doesn't really change the fact that it's bogus... And that's essentially all you want to know... A.
