I did try encoding a few chapters of a DVD rip for PS3 using the preset for it in Handbrake and the quality wasn't comparable to what I've done for the

TV though the PS3 is hooked up to a 1080p plasma while I use the

TV on a smaller 720p LCD. Streaming (from a year old Macbook using 2.2 GHz Core 2 Duo) to the PS3 over a wireless N network was also very choppy--as others like yourself have reported success, I'd love to know what I'm doing wrong.
