I am building some very low end media directors for secondary bedrooms. On a celeron 1.8 Ghz with a PCI Nvidia NVS 200 card (very very old) I am able to view SD TV channels in Mythtv, but HD channels are choppy, which is probably normal given the hardware.
I use the 96xx series nvidia drivers (which was a challenge in itself because the latest version simply would not work).
Since these computers are not even connected to HD capable TVs (but to computer monitors), I'm wondering if there is a way to tell MythTV to scale down the 1080p channels (which I get through HD Homerun) and send them to the MD as a 480p stream?
If that's not possible, is there a way to specify different channel listings per MD (by fumbling in some config file?), basically hide different channels on each MD. Then I could simply have the HD channels available on my high end MDs (in the living room) and on the low end MDs I could show the 480p version of the same channel (which exists for each channel), then it would just work.
PS: I gave up on using the HP T5700 thin clients to watch TV. Even after adding an Nvidia card through the PCI extension slot, video playback and low def TV was choppy. I guess the computer itself is just too slow (1 Ghz). But other than that they make a fine low cost low ($50 on ebay) power use MD for places where I need only music and external applications (web browsing, remote desktop). The Mythtv wiki says that T5720 are suitable, but I haven't gottent my hand on those yet. They are only slightly more powerfull than the T5700 too...
