Since Encore CS6 is no longer available, I use TMPGEnc Authoring Works 6. It is $99.00 for the PC only. It has many built in menu options. You can also create your own menus. When you burn your videos to DVD, Blu-ray, AVCHD, etc. Authoring Works reincodes the videos. I do not see any loss of video quality.
Actually, Authoring Works uses smart encoding, which means that it re-encodes only those frame(s) that the program deems necessary to do.
If files are dvd/bd compatible (such as Premiere produces) Tempg wont re-encode. It produces a lossless file.
