Seeing how little feedback I have gotten in the past few weeks about this Quicktime/MOV playback issue through MyPreMovieShow, I decided to take it upon myself to resolve the issue especially since I haven't heard back from SuperTal in over 3 weeks.
Ok as far as the fix....I distinctly remember being able to play .MOV 1080P trailers using the PreMovie show along with Quicktime late last year. So I did a little search and found this cool website below, which had the last 20 or so versions of Quicktime dating back to the very old 2.x version (we're in 7.6.2 now which does NOT work w/ PreMovie). So I tested the latest version available on that site which was 7.5.5 and it MAGICALLY worked, no crashing and the PreMovie Show effortlessly and smoothly transitions from Slides to Trailers.http://www.oldversion.com/QuickTime.html#download
(click on version 7.5.5 and make sure Quictime is the default player for .MOV)
I understand that SuperTal may either be too busy or may not have interest in maintaining his application going forward, but that's why we (users of his app) should pitch in some cash together to keep this wonderful app alive, or have someone else work with him to update and maintain the code. As of right now, the code is not updated so it will NOT work with the any of the 7.6.x versions of Quicktime, also it would be nice if we could get the software to recognize and play MT2S files since many of us use Volley's excellent highdef custom intros.
I will go on record that I will agree to pitch in an agreeable donation amount to keep the code updated so we can all use this app in our dedicated theaters for years to come. I hope to hear back from SuperTal and at least get his feedback, and let us know if he ever plans to maintain and update his software.
