Help! Almost everytime I rent movies from the Block-Lack Luster-Buster store they only play in B&W with a rainbow moire' pattern. All I want to do is watch the overpriced lame movie in color. I have a fine, low miles JVC vcr, #HR-D151-U, and a 5 year old Toshiba CX-2780A tube. I have no need or desire to tape this drivel. Please help! Thanks. John
