Wrong audio freq. in MPEG2 files

[mdorion]

I have a problem generating DVD-compliant mpeg2 files.

I record at NTSC DVD Ready settings (either high or low res). In either case the audio frequency is set at 48000 hertz (which is what the DVD spec mandates).

Still generated mpeg2 files seem to have 44100 as audio freq (or at least that's what Ulead Movie Factory 2 thinks). Which then requires re-encoding before being used to author a DVD.

Is this a known bug? Any workaround?

Thanks in advance.

I have not seen this in the past, what are your hardware specs? the device you are using to capture audio might not be cabable of recording at 48khz

My Tuner card is a WinTV-Go (PCI). My audio is Advance AC97 on-board.

I can record at 48,000 with Intervideo WinDVR2 so hardware is probably not the issue!

that is really odd because as you can see in my first system I have the exact same setup and all of my mpeg2 recordings are in 48 khz. Have you tried any other encoding software like, tmpgenc or (damn i cant remember its name there is a thread in the support forum about mpeg audio sync issues that names some other encoding programs but its late and I cant think of any off the top of my head). You might want to check the log files and make sure that snapstream is saying the audio is being recorded at 48khz if the logs say this but the file is otherwise then there might be an issue with snapstream.

Intervideo might not be using your sound card at 48khz but instead taking the live stream from it and resampling to 48khz when it encodes to mpeg. Snapstream can only record audio in formats that the audio card supports

you might want to try updating the drivers on the card to the latest

Upgrading to 3.2 beta fixed the problem.
