Recording Forex real time charts from PC output to CD/DVD

Hi,

I am a forex trader and I would like to record the real time charts on my PC for later viewing. below are my preferences.

1) Record it on to my PC as a video file.
2) Record it on the CD/DVD on the same PC. I do have a dvd writer.
3) If above two are not possible then record it to a external source, may be a DVD recorder or something else.

I would like to understand how can I achieve this as I really need this charts for review at later time .

Any help / sugguestions in this regard are very much appreciated.

Thanks for your time.
