Hi, I am running on Windows vista and can't get closed caption to work with old commercial DVDs. Those CC show up in stand-alone DVD player when play on TV but not on DVD drive with a computer. i have tried windows media center, powerdvd, and a lot of free software for DVD watching on computer. I start to think the problem is Vista. I find that some functions can just stop working after windows update. Does anyone know what is going on? Is this Vista problem or DVD playing software? Driver?
