I've been playing with the "Output to AVI" function of Showtime, reducing the output size whilst including audio of various qualities. Sometimes as it's adding the audio, the progress bar gets to 50% and then fails with the mesage "Error AvisaveV 2147205011" Doing some research on this indicates that it's something to do with the header of the AVI being written. Can anyone shed any light on the causes? I suspect it's due to me selecting odd sizes for the output. The default is 320 x 320 and I thought that reducing this by 50% to 160 x 160 would be acceptable but this throws a wobbly. Strangely some other settings such as 150 x 150 do work.
