I had the same problem where dvdrip detects the wrong resolution.
I found a way around the problem.
This particular DVD showed the resolution as 352x480 on the "Rip Title"
screen after reading the table of contents.
I knew that was wrong .
After ripping it I double checked the resolution by using the tcprobe
command against the vob file:
$ tcprobe -i ./vob/001/ram-001.vob
[tcprobe] MPEG program stream (PS)
[tcprobe] summary for ./vob/001/ram-001.vob, (*) = not default, 0 = not
detected
import frame size: -g 704x480 [720x576] (*)
aspect ratio: 4:3 (*)
frame rate: -f 29.970 [25.000] frc=4 (*)
PTS=0.0653, frame_time=33ms bitrate=6800 kbps
I got around the problem using the "Clip & Zoom" screen.
In the "Zoom" boxes enter the correct Width and Height.
In this case 704 and 480.
Then click the "Generate Preview Images" button and continue to the next
screen.
After normal transcoding the resulting avi file is 704x480.
I checked it using tcprobe:
$ tcprobe -i ./avi/001/ram-001.avi
[tcprobe] RIFF data, AVI video
[tcprobe] summary for ./avi/001/ram-001.avi, (*) = not default, 0 = not
detected
import frame size: -g 704x480 [720x576] (*)
frame rate: -f 29.970 [25.000] frc=4 (*)
audio track: -a 0 [0] -e 48000,16,2 [48000,16,2] -n 0x55 [0x2000] (*)
bitrate=224 kbps
length: 163722 frames, frame_time=33 msec, duration=1:31:02.857
Of course this works when you want the avi to have the same resolution
as the original file.
