Bandwidth shouldn't be an issue, BR video+audio nominal rate is 48 mbps (and thats as much as it can get), this is just 6 MB/s. You should be able to sustain this rate on a 10/100 LAN (not to mention Gbit). If you have issues I would say that network wouldn't be the bottleneck.
Specs on your Sony BR-Player says "MPEG-4 AVC (.mkv, .mp4, .m4v, .m2ts, .mts) : BD/DVD/CD/USB/DLNA" so in theory your HD MKV rips should run fine.
Nonetheless, feel free to post a sample of your problematic rips and I can double check to see how they run on the AIOS.
