[DVDnav-discuss] [PATCH] "dvdnav_jump_to_sector" as an alternative to "dvdnav_time_search" (REV 1: handle delay when reading directly off disc)

Thanks! Glad it worked.

> I noticed the following with a particular DVD:
> ERR:cell not foundA-V: -0.200 ct:  0.047  18/ 18 13% 13% 32.8% 0 0

I'm not sure, but I'm going to guess there is some sort of
copy-protection issue with the DVD. There are errors early on in the
stack trace (excerpted below) -- before it invokes the jump_to_time.

>From what I can tell, vm.c is failing to find the PGC in the
VTS_DOMAIN. The "cell not found" error occurs when trying to find a
cell in the PGC. If dvdnav couldn't find a PGC before, then the cell
would definitely not be found either.

If this is a commercial US DVD, I can hunt down a copy in my libraries.
Alternatively, you can post the binary IFO files. They're generally
shorter (< 100 KB), and I can investigate further. The files would be
VIDEO_TS.IFO and VTS_01_0.IFO (based on the error trace).

Hope this helps
