2015.3 Enable accelerated Intel h.264 decoding - Root of many problems?

Disabling "accelerated Intel h.264 decoding" may address some problems with 2015.3.

Preferences - Media.

On my very small test project (for which I submitted a bug report) this feature kept a multi-track (2x MTS and 3x WAV) sequence from playing back responsively, sometimes taking a full minute to begin playback.

With my large project (600 MB) I can not confirm 2015.3 is working well enough regardless of the setting, but it was previously unable to load all assets, having leaked my 64GB of RAM before finishing loading (in contrast with 2015.2 which loaded into 48GB of RAM). So it is working better than before, although I dunno if "good" yet. (And yes, there's another bug report for that problem too.)

Anyone having trouble with 2015.3 should look at disabling this feature to see if it helps.

(If Adobe gave us bug-report IDs I'd include them in this email so Adobe could more easily update the bug-reports.)
