Fix DVD format merges to preserve chapter metadata

Browse Source 
Removed -target ntsc-dvd and -target pal-dvd preset flags which
strip metadata including chapters. Instead, manually specify all
DVD parameters (bitrate, maxrate, bufsize, format) to maintain
full control and preserve chapter metadata.

Chapters now retained in both new 'dvd' format and legacy DVD formats.
