What model of Humax?
Some models have a USB port that can be used to copy recordings from the unit's hard drive to a USB drive. Though if it is a HD model you will not be able to copy HD recordings in a playable format as they are encrypted without installing some custom firmware on the machine first.
If the Humax has a network port and is connected to your router there may be options to copy over the network, again only SD recordings are likely to work though.
If neither of those options are available about the only way to copy stuff off is to connect the Humax SCART output to a video capture device plugged into the laptop and record everything you want in real time onto the laptop.
