Hi, I've read a lot of posts that say DVD deinterlacing techology has advanced a lot in the last couple years. Have players really advanced so much that it would be worth replacing an older model with a new one? Specifically, I use a Sony 9000ES with a Sony 34XBR2. I've been happy with the performance but wonder now if I would get an even better result with a new player. Has the performance of the 9000ES been outpaced to such an extent?
