I purchased this unit to convert my vhs tapes to dvd with my computer. I was trying to use a Dazzle dvc100 usb converter that came with Easy Media Creater 10 to caputure the analog audio & video to the computer. There were a few problems I had using that setup. I was able to work through all of them except one. The audio & video were never in sync on the computer & really out of time on the burned dvd.
I bought a firewire adapter card for the computer & the advc 300 for the digital conversion of the analog signal & everything works great. The advc 300 was very easy to use & hook up. I have used it as a stand alone unit for conversion only, and the dvd's actually look better than the tapes do. I'm using the same equipment for playback and capturing, but the dvds still look better. After a few a & b comparisons, I see it's the rock steady, uninform output of the advc 300 that makes the difference. It really does a good job removing noise, jitter & uneven brightness from the analog signal. And, the audio is in exact sync with the video. The manual states it has circuitry just to keep the two in sync & it works.
Last week, I loaded the advc 300's software on the computer. It's not necessary to use to get great results, but I believe with some careful small adjustments of the software, I will be able to get even better results from the converter. You can adjust color, brighness, contrast, etc. to compensate for poorly exposed scenes.
This device is a real pleasure to use. You will be surprised how good a old video signal can look when processed with the advc 300. Highly recommended.
