As long as I remember, mplayer always interpreted subdelays opposite to
other tools.

Btw I *really* suggest you not to use -dumpsrt for srt-to-srt (or any
other kind, for that matter) conversion; better use "srttool" (e.g.
srttool -d -5 -i input.srt > output.srt") (it used to go with transcode
package, if you can't find it, I can send its source) for
non-interactive changes and subtitleeditor for interactive changes.
