I just encoded my avi to MPEG2 format and it has those scan lines or something. Was it a mpeg property that caused this? There must be a way to have clean looking.
When i zoom out to 50 in windows media player you really cant see the lines
Sounds like you are seeing interlace artifacts.
Watch this media on a television, you likely will not see these lines. Your computer monitor is progressive scan; your television is interlaced. The default MPEG render settings are interlaced (as they should be for most video) and therefore, you'll see artifacts when watching interlaced media on a computer screen.
I wouldn't expect it to look that good in WMP. Try watching it on a DVD-RW to see how it really looks. Or DVD-A. Although, it seems like I've heard this complaint before. Try searching for WMP questions.
