Just purchased the dvd boxset of Stingray from Blackstar. However the first volume plays the copyright notice and the carlton logo then locks up. Volumes 2,3,4 and 5 all play without any problems. I've been sent a replacment boxset and it has exactly the same problems. Currently using a Proline 1000 as my R2 player having a dedicated Pana A310 for R1 discs. Anyone else having problems playing the discs using the Proline or anyother R2 machine?
