Thanks Alan East for your comments with REF to The Buddy Holly Story.
Likewise, I have found the 'juddering' on this film a right pain. I have not bothered to buy the blu ray. I have owned it twice on dvd format, & in both case's the juddering exsists.
The fact that the Powers at be haven't bothered to sort this problem out for it's 'high definition' release is a frigging disgrace. Thanks again for your honest input with regards to this film.
