Anyone use KMPlayer -

It not only plays almost anything you can throw at it, it captures analogue and digital TV signals from your TV card or USB device. The innards take a bit of getting used to, but if you like experimenting it can be very rewarding.

Another video converter-joiner is Mediacoder - it can convert and join or just join in copy mode like Avidemux, though I think Avidemux is better. Beware, like Super it plays funny browser tricks.

Lastly a FF browser plugin which allows you to download youtube files in higher quality MP4 format rather than crappy FLV.
