Since I can't edit my posts, and this information might help other users in the same situation, these are the images in question:
openmips-2.1-gb800seplus-20140207_usb - Internal Tuner not working
OpenRSI-4.0-gb800seplus-20140208 - Internal Tuner not working
openatv-3.0-gb800seplus-20140202_usb - Working, but no in-built softcam support. I just picked a random nightly build, but the latest one works too.
In lieu of softcam support for OpenATV I just installed TSPanel and all is working perfectly. I wonder will the build of OpenVIX have the same issues??
