ATI Radeon HD 3450, deinterlacing (?) problem.
Posted: Tue Feb 19, 2008 6:54 am
I'm using ATI Radeon HD 3450 and in general the card behaves well.
When used with latest Cyberlink/ATI video codecs it gives high quality, smooth picture from MPEG streams and with the ATI codec - smooth HD.
I do have one annoying problem:
- usually on sudden picture changes (quick fade to black, commercials etc.) something happens to deinterlacing - the picture becomes shaky, the movements are erratic. It looks like the card/driver is not merging the two half-pictures but displays them alternatively at a 25fps framerate. Very annoying to watch. After a while it becomes normal again, switching channels can also help.
When this happens GPU activity decreases by half (approx).
I link this with deinterlacing, because it happens always when deinterlacing is on (no matter bob, adapative) and does not happen when I turn deinterlacing off (weave). It happens on all Catalyst versions, including 8.2.
Anybody using ATI, having similar or other problems?
