@Kamal-Patel Slingbox... ugh, don't get me started. My brother bought one for my to set up locally so he can watch TV in HK. I've had nothing but trouble, since I don't use Windows.
Internet or power goes out? gg, now you have to spend an hour setting up the Slingbox again.
I'll look into Roku+Plex... whatever that is! 🙂 The reason I want to play around with MythTV is also so I can turn my HTPC into a DVR... but I don't want to pay for a tuner card 😢
