Hi Ian:

I have a Pinnacle DC10+ analog capture board and am using Screenblast 3.0 to capture the video. The audio is being routed through the sound card built into my MSI motherboard, which uses the 4 in 1 VIA chipset.

When I go to Screenblast Video Capture, then hold the shift key down when I select Preferences under the Options menu, then go the Internal tab, there is a Default Sample Rate option in the list. I have tried setting that to 48,000 from the Default 44,100 as well as saving an Audio Capture Format for DVD Quality, specifing 48,000, 16 Bit Stereo as the Attribute. Do you know if PCM (which is the only Format that shows up) can support 48,000?

I had downloaded the DVD-Lab demo to try it out and it complained about the audio not being 48K when the saved mpeg 2 file was imported into it, which is what prompted the original question.

I also found out tonight, that the 48K audio does not play when the captured video is saved to a DV NTSC avi file, but the 44.1K does.

Thanks...

Unfortunately I've never done any analog capturing, so my ignorance there is total!

So far as I know, PCM supports up to 192K, so 48K shouldn't be any problem - in fact, the spec allows 48K or 96K PCM for Video DVDs.

Regarding DVDLab, I've had no problems using MPEGs rendered with the PAL DVD templates - I allow DVDLAb to demux them and then everything works perfectly. I wonder if you've used an svcd template by mistake? It's worth perservering - I think DVDLab is a great product!

I don't understand the last line - I thought you hadn't got 48K audio? Can you play anything with 48K, like DVDs?

Hi Ian:

I can go into the audio setup and specify 48,000 and capture using it. Screenblast just doesn't want to remember that setting. If I reconnect to the capture device or exit screen capture then come back into it, the audio setup will default back to 44,100.

Thanks...

Sorry, it behaves perfectly for me! I tried playing with default.sfvidcap but it had no effect. It might be worth renaming the current version so that vidcap is forced to create a new one, but I'm not optimistic.
