Vertical bars in WMV movies and Profile/Settings question

I took an mpg file, converted to avi, edited, and made a wmv movie. I selected web streaming settings, and tried several different profiles (video for dialup 28.8-56; video for Lan/cable 100-768; video for web servers 28.8; and video for web servers 56). I kept getting vertical bands throughout the movie when I previewed it in Windows Media Player.

I have 2 questions:

1) How do I get rid of the vertical bands?

2) Which profile should I be using? (The movie will be available on a website)

Thanks very much in advance.

After converting the MPEG file to AVI, open the AVI file in Windows Media Player. Are the vertical bands visible here? If not then try making movie with "Video for broadband NTSC (768 Kbps)" and "Video for broadband NTSC (2 Mbps total)" profiles and see if you are still getting the vertical bands.

Bit rates now categorize the profiles. Video Edit Magic categorizes all profiles with bit-rate less than 756 Kbps under "Profiles for Web Streaming". To make movies for websites, select a multi bit-rate profile (a profile with multiple video streams) that covers the entire range of bit-rates of possible internet connection speeds. For instance, if you are targeting audience with internet connection speeds between 28 Kbps to 56 Kbps then select "Video for dial-up modems or single channel ISDN (28.8 to 56 Kbps)".

In many cases, selecting a profile for all possible internet connection speeds is not possible. Another solution is to provide two-three WMF files made at different bit-rates for covering up the entire range of internet connection speeds. You will have to experiment to create WMF files visible to all internet users.
