Hi, does the license apply specifically to the kernellabs.com firmware file, or the header files released by Xceive (xc4000_firmwares.h, xc4000_scodes.h) ? In the latter case, it should cover my firmware file (dvb-fe-xc4000-1.4.fw) as well, because it is generated from the same headers. Also, it is no longer generated from the Leadtek Windows drivers (like it was in the past before I had access to the Xceive header files), so it should in theory only be licensed by Xceive, rather than Leadtek. > Hmm...

Therefore, it only works with the demodulator used on the PCTV 340e, which is using that frequency, but not with the Leadtek cards with zl10153, since those require 4560 instead. It also seems to be missing some standard and firmware type flags. I am not sure if those are responsible for the I2C errors, or simply the lack of the analog firmwares. Perhaps the latter if the errors do not occur with the (currently DVB-only) PCTV 340e. > Such change shouldn't affect devices with zl10153, as this demod doesn't > call tuner's get_frequency(). The get_frequency() change is not an issue, the kernellabs.com firmware that is now the default and part of the kernel packages does not include data that is required for the Leadtek cards to work. > However, if the firmware doesn't work properly with PCTV 340e and/or > Leadtek/Xceive cannot grant a license to redistribute the other version > of the firmware, the best would be to rename the firmware file used > by Leadtek devices to dvb-fe-xc4000-leadtek-1.4.fw, in order to avoid > confusion. Although I did not test it, the firmware should work with the PCTV 340e as well. It definitely does with the Leadtek devices in DVB-T mode, and on the PCTV 340e the only difference is the IF (5400 vs. 4560). -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
