DVD-drev på PC og DTS lyd.

Does PowerDVD 5 support DTS ? try going from AC3 to wav then re-encode wav to DTS.

Here ae some details from the online 'help' section in PowerDVD:

Dolby Digital (AC-3) audio support for DVDs
Sampling rates: 32, 44.1, and 48KHz

DTS audio support for emerging DTS DVDs
Sampling rates: 48KHz
Decodes DTS audio signals

It indicates to me that the DVD-drive might not be able to handle/pass on  Sampling rates which are 48 KHz - or what do you think, Sturman ??

Think you may be correct, but it may also be that something is going wrong when you are converting it. Maybe there is something on www.vcdhelp.com that can help you out. had a look on their myself, and the suggestions i have seen are pretty much the same as i have given you - the try to convert to wave and re-encode one. might be worth a look around to see if there is anything else that may help.

Might even be worth trying it out in another DVD drive, one of your mates dvd drives for example.

It is not that I have done any wrong converting ! It's a sound problem with original movie DVDs which has additional DTS !! The AC3 soundtrack on the same disc is fine. I'll give you points anyway for your perseverance !!

cheers,
a better sound card is another road to take :)
