Variable bit rate seems to be the way to go in terms of getting the highest
quality recordings with the smallest file size. From the MythTV menus, it
seems that it supports it (since there's a mpeg2bitrate and mpeg2maxbitrate
setting when specifying encoding parameters).
However, from what I've seen empirically (by looking at file sizes), only the
mpeg2bitrate setting is used. Is this because of the hardware I'm using
(PVR-250, natch) or is this a bug?
The other question then becomes, if VBR is supported, why aren't there matching
mpeg4bitrate and mpeg4maxbitrate settings when transcoding to MPEG4?
Also, does anyone know of a utility that can do VBR transcodings of MythTV
format .nuv files :)?
