<DIV><FONT face=Arial size=2>It increases processor usage for me by about
10-15%. It also causes a problem for me when starting up a recording (either
starting live TV or when a recording starts). I sometimes get either a blank or
"crawling" green screen. If I escape out of live tv and reenter it will
eventually work, but of course I can't do that for recordings, and the first two
I tried with these flags wound up being all green. This effect seems worse at
lower bitrates. I'm using a Hauppauge WinTV 401 card (bt878). I'm also using
V4L2 on a 2.6.3 kernel. I havent' tried the DCT flag independent of the ME flag
yet, so I don't know if that would change the behavior for me.</FONT></DIV>
