I'm setting up a Myth box. I think that I want to use it like a DVD
recorder with a hard disk.
It was not obvious to me what the easiest way to burn DVDs from Myth
might be. I've settled on Myth Archive. (Alternative recommendations
Myth Archive takes a very long time to burn a DVD if the original
recording was not in a resolution suitable for DVD. As far as I can
tell, suitable resolutions for NTSC are:
Which of these last three are considered proper resolutions for DVDs?
For my purposes, it is unfortunate that the default resolution in Myth
is 480x480, not one of these. Now I know, it is easy to fix.
What bitrates make sense? I'd like to mimic the DVD recorders that we
have. They offer three quality choices: 2 hour, 4 hour, and 6 hour
modes. These choices select the resolution and the bandwidth.
Myth offers choices for two aspects of bitrate: bitrate and maximum
I'd like to know what to set all of these parameters to to get optimal
pictures within the constraints of 2 hour, 4 hour, and 6 hour capacity
for a single-layer DVD.
I'm using a Hauppauge PVR-150 with hardware MPEG-2. I'd prefer not to
transcode to DivX/Xdiv but maybe that would be worthwhile.
