#11572 closed Patch - Bug Fix (fixed)

Seeking backwards on DVDs sometimes seeks forwards

Description

Trying to seek backwards on some DVDs actually causes a jump forwards. This is caused by dvdnav_absolute_time_search assuming that NAV packets will be equally spaced. If they're not, the calculated sector will be wrong and actually be ahead of the current sector.

There is already a mechanism in place to compare the playback position after a jump with the required position but this didn't work correctly when seeking backwards due to type issues.

The attached patch fixes the type issues and allows the code to keep on zeroing in on the desired position until we're within a second of it (usually only takes a single iteration).
