[linux-dvb] Re: trouble tuning to any transponder -- working now

["Andy Alsup" <aalsup@usdla.com>]

Thanks for the advice Douglas. I made the changes you suggested, and now I
am able to tune some carriers on T5 from vdr. I don't know why anything I
changed should have mattered, but maybe I fixed something in the config that
I had incorrect before.

I am still having the same trouble with dtv_scan -- even on carriers that
vdr can now tune to--  but I can at least use vdr now.

A few more questions:

Does VDR actually use the Program Number for tuning?
Does the tuner have any low-end symbol rate specifications? Any reason I
should have trouble tuning to a carrier with 7000 Msps or less?

Thanks!
