I an using a Sony Vaio RX860 with built in IEEE1394 ports and a PAnasonic PV-DV910 MiniDV palmcorder. When I try to download something I have recorded to my PC I get Video but no audio during preview, capture or playback. Am I missing a setting, need a different sound card or what? I hae tried 3 different firewire cables and I get no audio with any. Any ideas? I've used Pemiere, DVgate, and MovieShaker and it is all the same, great picture, no audio.
