Yeah... that's what I thought. It should work for everything but mythtv and true HD video files.
You can adjust the mythtv playback settings in the regular setup menu in myth (not the main setup under computing) to the "slim" playback profile, and you can playback recorded myth stuff in all likelihood... but live streaming is going to be HD and probably break or be unwatchable.
Thank you very much! This old laptop worked well as a MythTV frontend for a few years so I have no complaints. I guess it's time to move onto the next machine.With luck the NUC will work well and I will be able to ditch the old laptop with the broken screen.
