[linux-dvb] saa7146 based TT1500 dvb-t doesn't find channels

[Oliver Schinagl]

Hi!

I'm using a TT1500-dvbt card, using the saa7146 budget_ci driver. On my 
tv-pc I have 2 partitions with gentoo and latest mythbuntu. Under gentoo 
everything works-ish. Under mythbuntu however, I cannot get it to find 
any channels using scan, dvbscan or w_scan. I copied the firmware for 
the tda10046h from the gentoo partition, thinking that may make the 
difference, but but even though binary different, they both report 
revision 29 (and it still doesn't work). w_scan does mention my tuner 
etc and even says 'signal ok' on certain frequencies, but eventually 
ends with 0 services found. I'm dumbfounded at to why I cannot get it to 
work, when the only difference is the OS.

Replying to my own message, I've found something to dig into further.

546000: (time: 00:43) (time: 00:45) signal ok:
         QAM_AUTO f = 546000 kHz I999B8C999D999T999G999Y0
Info: NIT(actual) filter timeout
554000: (time: 00:59) (time: 01:00) signal ok:
         QAM_AUTO f = 554000 kHz I999B8C999D999T999G999Y0
Info: NIT(actual) filter timeout
562000: (time: 01:15)
570000: (time: 01:18) (time: 01:19) signal ok:
         QAM_AUTO f = 570000 kHz I999B8C999D999T999G999Y0
Info: NIT(actual) filter timeout


Those frequenties that the signal is ok on, is what our dvb-t signal is 
transmitted on. Still don't understand why it does work under gentoo, 
but not under mythbuntu :S
