"MPEG Streamclip is also compatible with most MPEG-2 devices that use program or transport stream files, including FireWire MPEG-2 devices like Sony IP7/MicroMV,..."
"You can import transport stream files from FireWire MPEG-2 devices using DVHSCap or VirtualDVHS, two free applications available from Apple as part of the FireWire SDK 20 (developer.apple.com/sdk). NOTE: the latest FireWire SDK is not publicly available, please scroll down the list until you find the FireWire SDK 20, or click this direct download link from Apple: FireWire SDK 20. Install the package and you will find DVHSCap and VirtualDVHS in /Developer/FireWireSDK20/Applications/."
I.e. for geeks only. I have no first-hand experience about this.
