Hi. I don't know much of anything about much of anything when it comes to computers. But I am trying to use a Pinnacle Dazzle (USB) video capture card to transfer some video footage from VHS and DVD to the computer.

But the problem is that when there are sudden movements of the on screen video footage (camera moves abruptly, etc.) it messes up the conversion. The (captured) video will slow down and the sound will get choppy and then the video and audio get out of sync. I am wondering if this is due to the use of the USB cable, or perhaps another problem. I have read that using USB to transfer video/audio is inadequate. But I've also read where it can work well.

I only have 1.1 USB ports on the computer. Would buying some type of USB adapter to update to 2.0 eliminate my problem? Or would it be beneficial to get some other type of video capture device that does not use USB?

I have a Dell Inspiron laptop, maxed out at 512 MB of memory. Is it because my computer does not have enough memory that I am getting these crappy video transfer results?

Any knowledge or tips would be greatly appreciated. Thanks.

for video capture firewire is better than usb2 but your adapter probably helps by compressing the video on the fly, however usb1 is less than 1/10 as fast as usb2


meaning if your computer supports USB 2.0, you can get higher quality captured video.


I am surprised it works at all, you might optimize your computer and help it out some

No. Try not. Do... or do not. There is no try.

You need a fast computer to capture without dropping frames, but there's some good tutorials at videohelp.com.

I gave up on capturing from VHS with a computer. I use a cheap DVR now.

I had a USB-capture device a few years ago...trying to use drove me to purchase an ATI AIW :thumbsup:, which worked much better than the USB device. But that was some years ago and I was only using a 950Mhz system to capture (MPEG-1). To capture MPEG-2 will require more horsepower.

To move from USB 1 to USB 2...will cost you less than $10, e.g., http://www.newegg.com/Product/ProductList....tion=usb+2+card

AFAIK, synch problems have always been...but it helps to defrag your capture drive before starting. If you are using a box, it should take care of that.

Just thinking outside the box here, but as I said above, this is what I'm using now.


http://www.walmart.com/catalog/product.do?product_id=5027235

I paid $40.00 for it.

SV2000 WV10D6 DVD recorder. The picture quality is better than what I can get with a computer.
There are probably better models out there.

You can record from your camcorder, or VCR, directly to the recorder.
(according to the manual) Haven't tried it yet, but I plan to.
Right now I'm recording shows off my Dish Network system.
The quality is good.

The downside is the edit features are limited. But if you just want to preserve your home movies from your camcorder, or record shows off the TV. VCR, IMO this is the way to go.

Here is a review at videohelp.

I haven't had any problems with it yet.

Something to consider if you can't get the quality from your computer.
