While the subtitle renderer works well for most formats, it has issues with certain features of the SSA / ASS sidecar format (commonly used in fansubbed anime with various advanced techniques in use with newer series).
Similar topics have been brought up in the past (see:
http://yabb.jriver.com/interact/index.php?topic=82827.0) requesting an alternative subtitle renderer to work alongside the MadVR Video Renderer (like you could customise MPC-HC to do).
However judging by the jump from v18 to v19 there are visible changes to the JRiver subtitle engine that have improved SSA / ASS support, despite this there are some outstanding issues still which can be viewed from the following links.
To get around this issue, I switch from the Red October HQ profile to a Custom Video Mode profile which loads subtitles without issues (this also means I cannot use MadVR in JRiver).
For reference, the "Custom Video Mode" uses the Haali Video Renderer, LAV Video Decoder, LAV Splitter Source and DirectVobSub (auto-loading version). This setup presents subtitles as they were intended.
The MadVR setup uses the "Red October HQ" (RO-HQ) profile which uses the JRiver Subtitle Engine.
Subtitles are presented with no shifting and 100% default size.
The following links point to short clips (of limited anime series which represent issues prevalent in many other series) presenting both profiles and how they display subtitles, these have been recorded via Desktop Capture through Nvidia's ShadowPlay (no audio capture, just visual).
