30 | present in Hauppauge PVR-150 (and possibly PVR-500) cards that have | |
31 | certain NTSC tuners (tveeprom tuner model numbers 85, 99 and 112). The | |
f95006f8 HV |
32 | audio autodetect fails on some channels for these models and the workaround |
33 | is to select the audio standard explicitly. Many thanks to Hauppauge for | |
34 | providing this information. */ | |
