I don't have a Canon 830i, but I suspect that the method of recording will be the same as other Canon camcorders.
First of all you will need the appropriate cables. The first thing to note is that the 830i uses a mini jack AV connector. I suspect (but don't know for sure) that the Samsung uses standard AV connectors (Yellow, White & red). In this this case you will need a standard AV to AV-mini jack cable.
Connect the standard AV cable (red, White & yellow) to the coressponding connectors on your Samsung. Connect the mini jack to the Canon.
Set the Canon to PLAY mode and press Record Pause.
Press Play on the Samsung.
Press Play on the Canon
PS If the Samsung is a mono camera then it will only have a Red or White Cable in addition to the Ye;;ow one.
COMPAQ something or other with 500Gb Boot Disk, 1Tb external Firewire Disk, 4Gb Memory and a super duper sound card, 19" TFT Monitor etc etc etc
