For me it "just works". Here's my setup. Everything is connected by
100Mb or Gb Ethernet.
1. Master system. Backend with highdef recording (and NTSC), and
frontend, connected to high-def TV. Athlon64x2.
2. Second backend, no frontend. NTSC recording.
3. Part time front end. Nvidia card with Svideo to NTSC TV.
#3 will show highdef recordings and letterbox them, scaling them down to
NTSC. Everything happens just fine, on the fly. No transcoding needed.
I made no special modifications to the setup or the code. I was
surporised and pleased that it worked so nicely out of the box.
There's a potential rub, though. The computer driving it is primarily a
development workstation; it's used as a front-end when I'm not working.
And it's a dual-Xeon 2.4 GHz machine with 2GB RAM and hyperthreading.
It has a dual-headed Nvidia card so that the workstation is usable
even if the mythfrontend is driving the TV. I can change the aspect
ratio to anything I want (W key).
So...the on-the-fly scaling might not work at all with lesser-powered
machine.
