It's now been 3+ weeks since I've been able to use WatchTCM on my laptop (Firefox browser), and the part that is really confusing is that it stopped iN THE MIDDLE OF A MOVIE three weeks ago, with 5 minutes left. Sometimes that happens because my laptop's wifi adaptor is really crappy and decides it doesn't want to work for a bit, but refreshing the page did nothing and I haven't been able to stream anything since.
In response to the October mod post about the issue:
I just get the black screen right before the video loads and the status bar says "transferring data from www.tcm.com" until it just stops. It's taken me a while to even get google to cough up this forum thread because it's kind of an obscure problem, and I've tried every other suggestion for broken flash player/streaming, but of course as far as I can tell it's JUST the WatchTCM (I don't watch anything else, except YouTube which has HTML5 turned on...). I've tried closing my browser, restarting the computer, just about everything I could think of.
I also use XFinity, but can play movies just fine using the WatchTCM app on my Android phone (except 2 weeks ago when it was broken, but they fixed it within a day or two). I have to use closed captioning, so watching on my tiny phone is a pretty miserable experience.
