I've been checking out my WB DVD's and here's what I've found to be unplayable...(so far)
BROTHER ORCHID (from the GANGSTERS Vol. 3 set)
DESPERATE JOURNEY and UNCERTAIN GLORY (from the Errol Flynn Wartime set)
LUCKY ME and MY DREAM IS YOURS (from the Doris Day Vol. 2 set)
THE MALTESE FALCOLN...
I've been working through all my Warner discs and no problem yet. The upside was re-watching the incredible BLUES IN THE NIGHT. I'd forgotten what a weird and wonderful film that is. Great work by Don Siegel on the various montages and dream sequences.
