I've been using idvd to compress and burn several projects which run about 70-90min each. I've been exporting my timelines from FCP as quicktime movies - then importing them into idvd - then adjusting idvd's settings which allow me to use a single DVD. After burning, I'm seeing quality issues like a sublte screen flickering (particularly in wide shots), and loss of color vibrance. QUESTION: is this just the result of idvd compressing the file? Would using a dual layer DVD help as I wouldn't have to compress as much? Is there anything that can be done to yield better results within idvd?
