Serviio first impressions

Well, I'm trying Serviio with an Oppo BDP-80, and it's working pretty good.

Just two questions for now:
1 - Is it planned to support .ISO files?
2 - Is there any way to configure subtitle font and colour?

Thanks!

1) maybe
2) no, Serviio doesn't bake subtitles into the stream
