Hi, Welcome to Agoraquest

I guess you are using a Camcorder?

Firewire has great capacity/speed allowing the raw DV info to be transmitted and the interfaces are designed to allow your PC apps to control the Camcorder too making the whole process very simple.

USB is really for Pictures only or webcam use, quite a few posts on here regarding no sound when trying to transfer video. The USB conectivity will show the camera as a drive letter (memory stick) or as a capture device, it is a pain to use (in comparision) with lower quality results.

In summary, use USB to get info from the memory sitck or use as a really expensive webcam, for video use firewire. Good Luck

oh one more question, is there any difference in term of image quality ?

Yes.

and no.

You cannot really compare Firewire versus USB, since they are meant to do completely different things. Firewire is for video. You will get the best quality video images using firewire/i-link/IEEE1294. USB is for transferring still images stored on the memory stick.
In order to have a longer feature list, Sony has allowed you to stream video using USB. This should be used for webcam purposes only. The video quality is very poor, and is only 16 frames per second (versus 30).

It is funny that they don't try to push more data down for those who don't have firewire, the ability of the two is not very different, 1394 is 480Mbit/sec adn USB2.0 is 400Mbit/sec.

I am having a problem with my DCR-TRV140. When I connect through the IEEE1394 connection I can control the camera throught eh software on the PC but it won't capture the video. Any solutions?

I am using a DCR-HC32 Handycam. I found out how to download the pictures from the memory stick. I thought I could download the video off the tape so I can burn it to DVD. Can someone help me out here? I couldn't figure it out. Manual says use the burn to CD button on teh CAMERA but I can't find it on any menu.

Basically, what I read above is I need firewire right?

Any help appreciated.
