dvd (dts 5.1 ch) audio not playing on dvd player?

[chance_]

i have this dvd and i made a back up with dvd shrink... i think it had two audios and i left one of them which is dts 5.1... it plays on my pc but not on dvd players i have in the house. never had this problem. i checked up on other dvds i have... they have dolby digital 5.1 ch the dvd im having problems with shows dts 5.1 ch, doesnt play the audio.

having only dts audio on a back-up isn't a good idea IMO since some players won't support it. i'd go back and do a switcheroo with shrink audio tracks, test on an RW disc.

Nor is it compliant. There has to be at least 1 AC3 track on an NTSC DVD.
