Hauppauge DVB-S2 PCI Firmware Corrupt

[Douglas Mackay]

The firmware file dvb-fe-cx24116.fw - MD5 Checksum 9950fe612d47217e6068f7141de225b0 is corrupt.

Looks like the firmware was extracted from 88x_2_122_26109_WHQL.zip using the instructions at https://lists.ubuntu.com/archives/kernel-team/2009-April/005181.html. However these instructions are incorrect firmware v1.22.82.0 should have a md5 of b728b5d635393a4081e87d30d87a7632
