KWorld ATSC 110 and NTSC [was: 2.6.25+ and KWorld ATSC 110 inputs]
Quoted 13 lines · stuart
V4L support for the KWorld ATSC120 is limited. There a numerous threads here which talk about the problems and some work arounds. The developers have talked about adding support but consider new features at the cost of an overhaul of the current driver.
Right now I believe you can not use both ATSC and NTSC tuners w/o power cycling your computer and bringing it up with (only) the appropriate driver. Also, I don't believe the IR receiver works under V4L. This card replaced the Kworld 110 and Kworld 115 tuners. If you can find these older Kworld ATSC tuners, I would buy them instead as I believe they are better supported under V4L (I also have a Kworld ATSC110 - but only use it for ATSC tuning as well).

Go here and read up on how people are setting this card up:
I'm using the Kworld 120 as an ATSC tuner and nothing else in a Debian mythtv slave back end system.
Stuart, while I don't know for sure, I believe that information about the power cycling is now obsolete and the driver for the ATSC 120 is working.
In any regard, such things are not related to the difficulties Bill is experiencing with his 110 card. I'll detail in the next message.

The OP was talking about the older 110 to begin with...so he already has one ;)
On my setup, with an ATSC 120 (not the 110), power cycling or rebooting is still necessary to switch between analog/NTSC and digital/ATSC modes. Trying to load both DVB and V4L drivers either renders the card inoperable, or one or the other mode simply won't work.
In my case, for example, loading the analog driver (modprobe cx8800) followed by the DVB drivers (modprobe cx88-dvb) results in working analog mode, but digital mode is defunct. Rebooting and loading either of the two alone results in that mode working fine indefinitely.
Has there been a change to the driver that I'm not aware of? I'm curious...

Ah, ok. Thanks for the report Vanessa. I must have been thinking of
something else -- sorry for providing that moment of false hope :P
