DVD freezes in one spot during playback
I have an 1hr:45min instructional DVD I am trying to put out. I have tried burning using both verbatim and memorex DVD+R double layer DVDs with the same result.....ie at approx 40 minutes in...the playback freezes for about a second or two, then contuniues playing.... playback is on a panasonic tv with a built in DVD player, and a Toshiba stand alone ( consumer)
I have both used "burn from disc image" and used the verify option and everything was "sucessful" according to the computer. I even checked though the disc image and everything was correct.
Yet when I play it on my portable, there's no freeze. I am baffled and very frustrated. I also tried to have the DVD duplicated and the duplication facility said there were errors in the 1st layer.
Does anybody have any suggestions or similiar problems? I read in one earier post to have the DVD drive in the computer replaced. Should I do that or should I try a 3rd party burner be better, and if so...which one?
Any help, comments, suggestions would be greatly appreciated.
Thanks
