Does this mean SNR will/can now be calculated for the Fusion HDTV 5 Gold card? I quote Mac M. "This is because I have not found a method to generate a signal strength that I like. Signal strength is not directly available from the lgdt330x chip. The driver always returns 0." -alan Taylor Jacob wrote: >I have been very busy with work today, and would have posted this earlier.. >Sorry. > >Here is the "cleaned up" patch for adding support for the Air2PC/Airstar2 HD5000 >(LGDT3303 Frontend). > >http://www.digitalregime.com/patches/hd5000-cleanup.patch > >Changes to note from the last one I submitted are: > >- I have tried to impliment the SNR for the LGDT3303 since it appears to be the >same formula for the 3302 and 3303.. > >- I have also tried to impliment the signal level based on information I was >provided by BBTI..
