Before upgrading to the 1.0.0.2261 version I was able to play episodes of AC3 without issue. I am unsure whether it was natively supported previously or whether the transcode just worked better but I can now see it is marked as 'Audio:Transcode (aac)' while streaming and it stutters constantly giving me 'performance is not enough' errors until it makes me restart the stream. I assume it has always converted AC3 to AAC automatically with my set up though.
I have the same experience while using chrome browser streaming on my PC or my Nvidia Shield. Nothing else on my network or configuration has changed and I've tried restarting everything to resolve the issue. The really strange part is that my Synology doesn't even seem to be maxing out its processor when transcoding yet it still fails. I would definitely roll back if I could but it seems there are no clean ways of doing this.
Any insight, help or corroboration would be appreciated.
