I too noticed the poor quality of the video image above 376*288 on my 660av, after reading around on the net I discovered that when your AV only has 1meg of VRAM, the portion left for video (512K) is not large enough to hold the full image and so every second line is a duplicate of the line above. This is understandable, but it annoys me that this 'minor detail' was absent on the fact sheet posted to the net on the release of the AV's. This does mean that the 660av is really unusable for titling or video conversion, which doesnt upset me greatly as I didnt buy it for that, but perhaps others had that in mine and are now rather disappointed. -- Andrew Bevin andrewb@nezsdc.icl.co.nz Local Govt Group, Fujitsu New Zealand "I have a plan so cunning, you could put a tail on it and call it a weasel!" - Blackadder
