Best DVD making software?

I posted another question similar but asking more specifically about encoding but here just list what you think is the best program to create and burn DVDs, what do you use and also any recommendations. Details: large videos 1gb up to 4gb in mostly .mp4/avc but some are .mkv format and the only program that even will accept .mkv is ConvertXtoDVD. I need the best software and cost is not an issue. Adobe? Sony? Please advise
