Thanks for your reply.

These two "firmwares" are also needed, right:

- v4l-cx2341x-dec.fw : CX23415 decoder part
- v4l-cx2341x-init.mpg : decoder initializer

Multimedia video controller: Internext Compression Inc iTVC15 MPEG-2 Encoder (rev 01)
Subsystem: Hauppauge computer works Inc. WinTV PVR-350

Are there any technical or legal issues for all these firmware files not to be included downstream within "linux-firmware" package, with the rest of firmwares?
