Unfortunately, the only real workaround is to export to a format other than h.264. If that's not an option for you, then your best bet is probably to keep working in CC7.2.2 until the patch is released.
Crud! I can't remember the last time I exported to anything other than H.264.
That is what I upload to YouTube. And Vimeo.
It is also what plays on my HDTV via the USB port.
Worse yet, my one remaining paying client uses a USB stick as well. And H.264 is the format for those videos.
Let's hope that this gets fixed in a big hurry. Or CC 2014 is a boat anchor just sitting there taunting me unless it is for a small project where I can export a lossless file that can be taken into 7.2.2 for export.
