By 'standard', that means MPG, MP3, JPG, PNG and so forth. FLAC, MKV, AVI, TS, OGM and the like are considered by the consumer electronics industry to be 'piracy enabling' formats. The odds of finding them supported in a consumer interoperability format for streaming files are vanishingly low.
Call me cynical, but there you are.
Individual devices may support these types of files via disk or USB because each copy has to be generated for each individual use. Streaming may very well be supplying more than one viewer at a time (so they think).
Standalone software for DLNA serving can get around the DLNA restrictions by serving the 'rogue' formats by UPnP so that, if the receiving device supports them, they can be played.
The Oppo supports MPG (1 and 2) video (with any of MP2, AC3 and 16-bit PCM audio), MP3 and PCM (16-bit) audio and JPG and PNG images via DLNA and MKV via UPnP over its ethernet connection. Within the MKV wrapper, it additionally supports H264/AVC (Mpeg 4, Part 10) and XVID/MP4 (Mpeg 4, Part 2) with any of AAC, MP3 or 16-bit PCM audio. Anything else (currently) needs to be converted by the mediaserver software to one of those formats or wrappers or formats within wrapper.
Oppo is NOT really responsible for the deficiencies of DLNA and I'm quite pleased that they undertook to enable ANY functionality of DLNA/UPnP over the ethernet connection at all.

Wow!

Thank you for the detailed response - it is in line with the results of further tests I performed last night. Ultimately was not able to get the WHS to serve up anything but mpg so instead quickly installed TVsersity on another PC to test the OPPO and it saw/played MKVs from that PC just fine.
Older MKVs played fine however the newer ones were pixelated/macroblocking, similar if you have seen the difference in CoreAVC 1.9.5 to 2.0.0.
I am highly impressed OPPO was able to get in DLNA/UpNP functionality as it seems promising - if OPPO fixed the x264 codec playback I'd be grateful!
