The current DVD drive firmware is 1.15. The TiVo software is 5.42. Both were updated shortly after setting up my unit in the past week and a half (from 1.08 and 5.41). On another note, my unit started to pixellate and went blank for a second toward the end of a program I was watching tonight on live TV. The entire glitch lasted about 5 seconds and was captured in the recording I had set it to perform at the same time. Sigh.
