Wrong HD to buy?

I ran out of space on my internal HD, so I bought a 640 GB USB external HD. I saved my project as an avi file, but the video is "wavy" and the audio is WAY out of sync.

The source vid is AVCHD. Is USB too slow to read video correctly, or have I done something wrong? My internal drives are SATA drives.

Could I transfer the source files to this external drive, and use the internal drive to make a DVD?

I run video from external USB drives all the time. Seems unlikely this is the problem. (You do have a USB 2.0 port that the drive is plugged into, I'm assuming...)

Barring something odd with the USB connection, better guess is how you created the avi file. Can you describe that? Does the .avi file in question play fine on your internal drive?

I clicked on "Make Movie" and chose the USB drive as where to send it. It's only a 12 minute video and took about an hour to render it as an avi file- is this OK?

I am using a MB with a 3.0 MHz core duo whatever.

On my machine everything slows down if I do not keep 1) the Windows pagefile 2) Vegas input media and 3) Vegas output media on 3 different drives.
Here Windows seems not to like reading from and writing to the same drive.

If you have a big enough USB memory stick or card try to render to that instead.
For test you could just select and render a minute or so.

That's basically what I am doing, but trying to make an avi file on my USB HD results in normal audio, but video playing at half speed!

A couple thoughts:

1) Have you tried playing the file on both the external hard drive and your internal drive? If so, were the results the same?
2) Try rendering just a few seconds of the video using the same settings you did for the larger file. Same results on both drives? If you have a way to post this smaller file (Vimeo might work) then others could get the original file and see if the playback issues occur on their machines.
