This is the way I usually do it too. It works and avoids the time
consuming recoding step. The only disadvantage I found is that the
thumbnails in the DVD menues have the wrong aspect ratio (at least with
TMPGEnc DVDAuthor).

I've recoded a 480x576 4:3 recording with black bars on the top and
bottom to 720x576 16:9 with the black bars cutted (72 lines at the top
and the bottom of the original picture) which kept the correct aspect
ratio and lets you view the movie in pan/scan format without black bars
on a 4:3 screen. If you want I can send you the TMPGEnc template file
for this via PM. It could be a starting point for a 4:3 to 4:3 recoding.

I use ds.jar on Linux and Windows. It works well (a little slow on
Windows) and gives useful information about the mpeg stream like the
average bitrate which you can use as VBR bitrate in TMPGEnc if you want
to keep the output file approx. the same size as the input file.
