Don't worry I did it over here and I didn't see any difference. If anyone is interested in trying it out just look in bt848.c:rgb_prog. target_buffer is initialized to the start of the field. To start in an odd line set : target_buffer = buffer + pitch; To start in an even line: target_buffer = buffer; I think what folks are seeing is aliasing effects. Enjoy, Amancio
