Devices get the block size via ioctl, but for a file the block size needs to be set. Default to 512, but optionally allow other values, like 2048/0x800 for ISO CD-ROM images. Also updated the comments in .DSC and .DEC files.

BerkelyPacketFilter seems to work. Some one else will need to use the BerkeleyPacketFilter as a template and implement the LinuxPacketFilter. I don't think it will be that hard, as they are simular.
