I've been able to do multiple transcoded streams as well. The only thing it seems to struggle with are a few of my blu ray MKV files that are like 40GB. I usually use Hanbrake to convert them to H264, and it doesn't have any issue with multiple H264 streams. Avatar and the Matrix are examples of the raw MKVs being a bit "too much" for the CPU. Who knows... Could be improved by software or something like that, but for now, when I find a problem MKV, I just have a special folder where I put my MKVs in... that way, I at least keep the raw MKVs for later, if I get a better CPU or something, and I have the H264 files accessible via Plex. This has only been an issue for like one in 10 blu ray rips.... So far I'm happy with the Avoton chip, and whenever its successor comes out, that should be the "perfect" CPU for all transcoding while staying fanless and low power.
