I've never noticed clicks or pops, either I have no missing audio in my recordings or a newer version doesn't have this problem? I've also not noticed any sync issues. > Note, also, that I say mostly in sync because I have found that I get > sections of recordings lasting between 5 and 30 seconds where A/V sync > is off by as much as about 0.5 seconds.

Perhaps its the output format your using?

I'll agree here, and boy is it annoying when you notice it. Whats worse is now I notice when original broadcasts are out of sync, some network shows are like this. For instance, the other day watching a Seinfeld rerun on one of my parents SD cable box I noticed about a .3s audio delay. ugh...
