Hello everyone. I am facing a huge problem trying to edit a DV file in Premiere Pro. Could anyone please help?

I am using an Nvidia VIVO card to capture a VHS tape. For this I resorted to Main Concept Capture tool, found in Main Concept MPEG Encoder 1.4.2. As I found out, the only way to keep audio and video synced was to put Main Concept DV Codec to use for the capture. I set DV type 1 and audio at 48kHz, 16bit, stereo. I tried two MJPEG codecs and even uncompressed video (for the sake of it) but all produced un-synced captures. Anyway, I captured more than ten minutes of tape to an empty, just-formatted NTFS hard disk as a test and was very pleased with the result: Perfectly synced capture, absolutely no dropped frames and acceptable quality. Trouble was still ahead of me though.

The captured AVI plays well in all media players (PowerDVD, Windows Media Player etc) from start to finish. But when I import it in Adobe Premiere Pro 1.5 it only appears to be just under 2'30" in duration! I recaptured and recaptured test files (some with 48Khz audio, some with 44kHz) ranging in duration from 1 to 10 minutes, and almost none was imported OK in Premiere. Most appeared to be just under 2'30", shorter ones appeared as just over 1' and only really short ones were imported OK. Also, when I imported the first captured clip in Vegas Video (Trial Version) it was imported OK as far as duration was concerned, but with no audio! VirtualDub importes same video correctly in its full duration but complains about not being able to extract or edit audio. So, I can have a perfectly captured DV file, but I can in no way edit it and convert it...

If anyone could please help I would be more than grateful
Cheers to all
