No...no hacked aTVs.....played with ATVFlash a year ago, but it just didnt take with me. Personally that is.
I use MakeMKV to get the BRay to disc as a mkv, then either HB or MKVTools to take it down to 720p specs and m4v. The HB setting I got off here somewhere....
mixed-refs=1:b-adapt=2:b-pyramid=none:trellis=0:weightp=0:
vbv-maxrate=5500:vbv-bufsize=5500
And like I said, Im toying with the constant quality setting. Just trying to max the files to the best result for the aTV. ReRipping a file now using constant quality of 18, as the 15 like I said was rejected outright by the aTV like you mentioned.
BTW: does it make a difference B&W or Colour films with these settings?
