Hi everyone! I have Sony PFM500A2 plasma TV. Recently I bought progressive scan JVC XA-S90 DVD player. I used it for a month using regular composite cable connection. Finally, I decided to try progressive scan video and connected DVD to my TV thru component cable that came in with DVD. My TV has a BNC input, so I used RCA-to-BNC adapters for connection. What was strange is that after connecting with component cable, picture became much worse that with composite. I had a lot of artifacts(small cubes)and bad black level picture. I must admit that TV itself has bad black level, but with component it became more visible. What is wrong? Thank you in advance.
