How the DVD is ripped seems to have nothing to do with the process, outside
of keeping the 16:9 720x480 pixel aspect ratio. Even if you had ripped in
720x480 4:3 the picture would still be squished and subsequent output to a
new 16:9 DVD would straighten out the mess.
>From what I can gather you are ripping the original and simply re-recording
to another DVD output. This is essentially nothing more than making a direct
copy of the video on the original...which regardless of original format is
still 720x480 resolution.
The original information for the video to playback in proper screen format
is located on the original disc, which is not the same as what is placed in
headers of an authored disc. The original header inforamtion is guaged to
command output for the original recording proper.
When a DVD is authored the program used is told which format 16:9 or 4:3 to
use before it is remuxed and demuxed to disc. Making a direct copy of your
original is not the same as ripping and re-recording any normal type of DVD.
In production run DVD's there are VOB files, etc. which hold this
information, and when you rip and re-record this information is held intact.
Your discs have a format of their own and the screen format is held in that
header information. Recordings to set-top DVD recorders is usually a DVD_VR
file, which is different than what you are getting with MCE. There are
programs and plug-ins for NLE software that allows the capture and editing
of the DVD_VR file. When the subsequent information is then written to DVD
for final output the program is told what screen format to use. This does
not happen automatically.
Your discs have only video information without screen format information
headers which make sense to programs like Nero, or any other for that
matter. You need to start with raw, or at least as raw as possible video to
re-author to a new disc rather than a simple rip and copy process. Otherwise
you will always get the same output as you are now getting.
720x480 16:9 video will always playback as squished looking 4:3 through
analog or DV outputs from an NLE or other editing software package to a TV.
This is because there is nothing on the output side to tell the video to
playback in it's true screen format - 16:9. The NLE editing software will
show the proper 16:9 inside the computer, but not for any form of output.
The only way to make this happen is to author to a DVD and tell the software
to output as 720x480 16:9, at which point the proper playback is then
governed by the DVD player proper. Without the information necessary to
playback at 16:9 the video will always playback as squished 4:3 regardless
of what DVD player you have for playback.
