Good news. If you're looking for sites why not expand a bit more into non-porn websites
Implement all the sites supported by WVD... Then maybe the ones from GoTube (the PSP app). Also don't forget some websites have mp4 streams.
PS: Don't completely avoid websites just because of onvp6 (just jot them down in the priority list). TCPMP plays it even if it's slow because it's based on ffmpeg and not very optimal (don't know how well it performs on the HD2 though). It would require a hell of a developer to get it right but who knows...
