I just obtained the product. I transferred a 2 hour vhs tape to a file on my hard disk. The resulting file is 22gigabites. My assumption was that the two hour tape would result in a file which would fit on a 120 minute dvd. Can anyone explain why I am having this problem and how to get around it. Thanks.

Its not a problem but just a musinderstanding of how DVD video works.

You propably captured to avi format which is fairly uncompressed video. The video on a DVD is highly compressed.
When talking about video you should forget about file sizes since they basically mean nothing. The important parameter is time length of the video. A standard 4.7GB DVD will hold 60 minutes of video at best quality. You can squeeze up to 120 minutes of video on the same DVD but it will be highly compressed and have poor quality. There really is no such thing as a 120 minute DVD unless you are talking about DL DVDs which can hold slightky less the 2 hours of video.
You could split the video into two 60 minute halves and burn to 2 DVDs and keep reasonable quality.
