I have three issues in MEP 2015 that I didn't have in MEP 2013. I just emailed this to Tech Support and will post any response I receive in case others experience the same issues.
Burning: After completing my multi-cam edit and entering Burn mode, I could burn a working DVD. However, I haven't been able to create a working Dual Layer DVD or Bluray. I need one or the other done by Sunday for a High Def presentation (it's a 2.5 hour 1080i performance).
Bluray disk: It seems to create the bluray fine, but the simple one button menu to play doesn't function once burned so there's no way to play it.
Dual Layer DVD: The burner recognizes that I've inserted a dual layer DVD but scales the DVD file size to 4481MB versus the 8152 available on the DVD. It’s trying to compress it to a single layer size despite knowing a dual layer disk is inserted. I went into the encoder settings and increased the bit rate to about 7000MB. When I burned direct to disk, it still created a 4481 size disk on the dual layer disk. I then encoded it to a folder and the folder size was 7000 mb so I tried to burn the dual layer DVD using ImgBurn but received an error that said "Unable to find any cells that could be used for the layer break". When I tried to burn it anyways, it still only used half the disk space and the quality was again poor.
Editing issues: I've been very frustrated with MEP 2015 since I "upgraded" from MEP 2013 last year. I've had nothing but problems that I never had. For example, I use the cursor keys for precise multi-cam editing but using the reverse direction cursor is so stuttery it’s unusable. The multi-cam 4 window view can be increased but the individual camera views can’t be increased large enough to view them well even on a larger monitor. It’s almost better to only edit two camera views at a time (so why then just not use MEP 2013?).
I've loved MEP ever since I switched a few years ago but I'm close to throwing in the towel because I've wasted so much time (and created so many coasters) over the last year with various issues in MEP 2015. I even spent the money to upgrade my computer MOB & CPU solely because MEP 2015 had more performance issues than MEP 2013.
