I found a concert on YouTube that I really wanted to keep so I downloaded it using the Firefox Download Helper add-on. The source file was a 720p MP4 but after downloading it I converted it to AVI before burning a DVD using Windows DVD Maker. The resulting DVD is very blocky when played on a domestic DVD player, admittedly onto a 37 inch plasma TV. When the concert is viewed on YouTube the quality is excellent but am I expecting too much for this quality to have been retained?
Would it make any difference to create the DVD straight from the originally downloaded MP4 rather than the AVI?
