Your failing channel is VHF channel 6 while your working channels are UHF. Is the Hauppauge Nova-T Stick supposed to work with VHF? Maybe an antenna or other reception-related problem with VHF? -Thierry -Message d'origine- De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] De la part de Mat

[linux-dvb] Force cold reset / firmware reload of PCI device (Nova T 500)

2007-11-14 Thread Thierry Lelegard
Hello, This has already been asked here but I can't remember if an answer was found. When you have a PCI device such as the Hauppauge Nova T 500, you upgrade the drivers and firmware (meaning copy a new file into /lib/firmware), you may force an unload/reload of the driver in the kernel but is the

IMHO, the Linux DVB framework serves two main purposes: - Common API for the zillions of DVB-S/C/T adapters - Common frontend for TV watching programs such as Myth et al. Dektec products address the market of professional & test lab applications using ASI input/output, QPSK/QAM/OFDM modulators out
