Disc skipping questions

[chele519]

I don't know much about blu ray technology so maybe someone here can answer this for me. I bought the Life set and have just been watching it to make sure the discs all play fine before my return period is up. I was watching part of it tonight when at one point the picture froze and then restarted about 10 seconds ahead. The disc is not scratched and the set was bought new. I backed up that section and have watched it a few more times and it did not do it again. Since it didn't happen every time, does that mean it is not the disc but is something to do with my player? Or does this happen sometimes with blu ray?
