Yep, Nero and Image Burn. Most of the other conversion/recoding programs end up using Image Burn to do the actual burns anyway so even if you use BD rebuilder or multi AVCHD they end up running it when the disk is made. I used to use a LOT of different programs when I first started burning CD's back in the day but most of the ones I really liked are gone now and Nero and Image Burn remain.
I don't think I've actually used ImageBurn to burn a DVD, but I build an ISO with it and then use CD-Speed ("other") for the actual burn. That way I get a trace of the burning process that show up in CD-Speed quality scans.
