Any way to quickly remove multiple "Set field indexes" from VOB?

[nhope]

Sony DVD Architect creates subpics that have have an apparently redundant "Set field indexes" command after the "Stop" command in this screengrab from DVDSubEdit:



Although not a problem on some players, this creates a problem on many players such as my Philips BDP2100/05 player whereby subtitles behave as if they are infinite and not finite. Without that line, subtitles stop as intended. I ripped a BBC DVD for comparison and saw that finite subpics didn't have that line after the "Stop".

I can manually modify each subpic in DVDSubEdit by memorizing the duration, then clicking "Inf.", then dragging the duration slider, then clicking "Yes" to add a STOP command, then dragging the slider, then manually typing the duration (pasting a number from the clipboard strangely sets that back to "Infinite").

Doing that for hundreds of subpics is going to be very laborious. Does anyone know of a faster way to remove all those instances of "Set field indexes"?
