I ripped some dvds using handbrake and am trying to play them back on the tivo via pytivo (wgw snapshot from a couple days ago). Everything transfers and I get video and audio, but it is stretching the vertical to fill the whole screen instead of just putting in black bars. I am the pyTivo.conf.dist with only the path changed.

Code:
transcoding to tivo model 648 using ffmpeg command:
/usr/bin/ffmpeg -i /mnt/media/itunes/Movies/Apollo 13.mp4 -vcodec mpeg2video -b 8192k -maxrate 30000k -bufsize 1024k -comment pyTivo.py -ab 384k -ar 44100 -acodec ac3 -copyts -f vob -

Seems stream 0 codec frame rate differs from container frame rate: 44100.00 (44100/1) -> 23.98 (24000/1001)
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '/mnt/media/itunes/Movies/Apollo 13.mp4':
  Duration: 02:19:44.2, start: 0.000000, bitrate: 1631 kb/s
    Stream #0.0(eng): Video: h264, yuv420p, 720x362, 23.98 tb(r)
    Stream #0.1(eng): Audio: mpeg4aac, 44100 Hz, stereo
    Stream #0.2(eng): Subtitle: text / 0x74786574
Output #0, vob, to 'pipe:':
    Stream #0.0(eng): Video: mpeg2video, yuv420p, 720x362, q=2-31, 8192 kb/s, 23.98 tb(c)
    Stream #0.1(eng): Audio: ac3, 44100 Hz, stereo, 384 kb/s
Stream mapping:
  Stream #0.0 -> #0.0
  Stream #0.1 -> #0.1
Press [q] to stop encoding


I am trying to decide if it is distorting by stretching the vertical or cropping

Any suggestions?

Unfortunately i've resorted to ripping the movies with the black bars in lieu of cropping them out. It really doesn't take up any additional space, just annoying. I'd really like a solution to this issue as well.

The aspect button still doesn't fix it, it gets better, but it's still not correct.

Then, presumably the aspect flags on the MP4 are not being recognized. You could try encoding to a size with square pixels, which would be about 640x362 instead of 720x362.

(Personally I just rip to MPEG2 without reencoding. Anything else, you're losing quality.)

If only I could come up with enough storage. I'm essentially trying to create a VOD library for nearly 500 DVDs and growing. That'd be 3TB+ in mpeg2.
