I don't get it. I have a 622 and it's had L449 firmware as long as I remember.
It is off alot of the time, and rebooted about once a week.
What's it take to ensure the system is up to date?
Hmmm...now with L511, on KDFW (my HD LiL Fox affiliate), I get audio skips in buffered playback. The video is unaffected. It is not happening on the other HD LiLs, and it's not happening on my 722 (which has L511 as well). A reboot did not fix it.
