say, have the later firmware done anything to address this ?? if I play the movie from the start, it works fine, if I skip ahead or behind I have to adjust the audio offset to sync the audio. I tried another movie yesterday, it played great start to finish, but any moving forward or back in time didn't work and paused or locked up the movie. is there a fix for this ?? is there a work around ?? my firmware is the one right before .10 and .15, on my z9x
