problem with .ifo on a home made dvd

[g386kin]

Hi,
I have a home made DVD from my friend.
In the DVD:
video_ts.bup, .ifo and .vob

vts_01_0.bup to vts_06_0.bup

vts_01_0.ifo to vts_06_0.ifo

vts_01_1.vob to vts_06_1.vob

Total 21 files.
when I play the DVD it will play from 1 to 5 and then stop without playing number 6. when I edit the vts_05_0.ifo and vts_06_0.ifo with ifoedit, I see no iformation inside. And I can play the vts_06_1.vob with winDVD. Can anyone help me with the rebuild or fix the .ifo?

Try using dvd decprytor to rip the disc to your HD. Then open the files with dvd shrink, select the movie only, and then back it up.

Basically, you are using dvdshrink to remaster the movie, it will recreate all of the files.
