Pinnacle Liquid is good but abit more expensive.
If yoou get the breakout box you can capture from DV and any other source such as composite, component, and s-video.
Its power depends on your computer and your graphics card so you dont need any other third-party hardware devices to make it do stuff in realtime.
For titles it uses titlew deko although you could import titles from any other title program as long as it was maybe a JPEG or TIFF file.
The DVD side of things is not bad and allows you to make menus etc pretty easily, Although with most editing programs it still takes time to produce your final product!
If you are just copying to DVD from VHS and not editing the material than you'd be better using a DVD recorder.
