I wouldn't know first hand, but I found this for you..

OMG... Stay away from KWorld!!! They use the the cx88 driver in Linux, but are not autodetected. The radio has never worked.

Hi folks,
 
System: Fedora Core 3 / AMD Athlon 1.4 / 1 GB RAM / nVidia 64mb video w/3d acceleration / KWorld V-Stream DV/AV Expert TV Stereo card with Conexant chipset. Sticker on the bottom of the card says: KW-TV883DVR-Pro
----------------------------------------------------------------
Has ANYONE been able to get a KWorld TV card to work? I have one and would love to have it working. On a "dmesg" dump, I get a message that the card cannot be autodetected and to pass the insmod option "card=xx" to workaround it ("xx" being the correct number of the tuner this card has..."14" is the one my card has I believe). Here is the relevant section of my dmesg dump:

Anyone have any ideas on how to pass the correct insmod option so I can see if it will work?
 
Thanks!

I have this card and the radio works great, much better than with Windows. You just need to pass card=16 to the driver like so.
modprobe cx88xx card=16 audio_debug=0 tuner=2
modprobe cx8800
 
I have to use the tuner option because I have an NTSC card, it should work without it for PAL.
 
I haven't got the IRda remote to work yet though.
