right now ot seems to be WITH scaling OR produces 4:3 1440*1080 files.
Patches aims at fixing that.

I suggest CinGG supports all valid BD-formats, SD and HDV anamorphic

yeahhhh ....

sounds like permission error?

hey, we did lpcm bd audio too some time ago! There must be little dropdown
menu with two choices ...

well, smart render is harder than it sounds even in linear transcoders
based on ffmpeg :/

piping all this info in correct manner using cingg's internal seems to be
beyond that *I* can do.

But we hopefully at very minimum can develop mpeg2_video encoding profile
based on mpeg2 high quality one. But this again require testing on real
media/player - due to bitrate distribution/rotation speed interplay not
emulated when reading from a file.
