--Cybernard 18:20, 29 December 2008 (CET) User cybernard reports: Using OpenSuSE 11.0 and 11.1 kernel 2.6.27.7-9 I placed the firmware in /lib/firmware, the same location as the ATI HDTV Wonder firmware. I tried to get thd HDTV over the air 8-VSB, I believe, but it doesn't tune. Signal strength is almost always 0 despite being hooked the same antenna as a ATI HDTV Wonder which works just fine. Mythtv see the card, but can't find any channels.

femon -a 0 
reports only "S" under status and the ATI HDTV Wonder status says "SCVYL"

Sometimes, not often, signal strength is 007d compare to fcd0 for ATI.  However, 007d is the signal strength that the windows driver reports, but id decimal form of 125.  This could simply be a scaling issue and multipling it by 256 may or may not help, but would bring the signal strength up to usable values since 125 to 127 offer perfect reception within windows.

Further more something is trying to load mt352
which results in:
mt352_read_register: readreg error (reg=127, ret==-6)
Also trying to load zl10353 resulting in:
zl10353_read_register: readreg error (reg=127, ret==-6)

Whoops!! The above is my fault I told "yast2 tv" that I had a DVB-T card instead of autodetecting the correct version of the card. I deleted the DVB-T card, and let linux auto-detect it.

Using Kernel 2.6.28.1 the card pretty much works, but still get below sometimes. Xine will tune in and watch channels, and mythtv will detect channels. However, mythtv reports that it can't measure the S/N ratio error code 22.

You should report this on the mailing list--CityK 02:49, 19 January 2009 (CET)

I did report it there also.

--Daveisfera March 30, 2009: I have installed this card on a Mythbuntu 8.10 x86_64 system, and once I installed the latest v4l-dvb source code, I am able to tune channels using the scan utility included in the dvb-utils package (the dvbscan utility in the latest dvb-apps source code always gives me the error "Unable to query frontend status") and I can watch channels using mplayer, but MythTV is unable to tune channels. However, if I manually added channels, then I can watch them using MythTV.

--Daveisfera March 31, 2009: I installed Mythbuntu 9.04 beta and the firmware and I am able to tune OTA ATSC channels. It also appears that the issue with signal/snr has been resolved, but there's still issues with programs like MythTV getting the correct values.

 Using the correct firmware and a new kernel the card works just fine.  It may/may not support analog, but here in the US there is only digital so it
is not important.  The signal strength doesn't report correctly.  However, I have successfully got it to work with Mythtv with no problems other
than the warning about not detecting signal strength.
