Yeah, me too. The main reason I put the rotor position approximation
code in there at all was for the benefit of my dst, since it definitely
needs the retune. Are you actually using your dst cards? I have some
patches pending to the dst driver that improve the reliability of some
aspects of tuning, but I think Manu's been too busy fighting the
multistandard/8psk fight to get them into the main v4l-dvb repository --
I think he has his own stash of pending commits himself, too. My patches
deal mainly with the tone/power commands, so if you're having problems
with those you might want to try them. Oh, also, I enabled 5-byte DiSEqC
for USALS rotors on cards which support it, and lots of ioctls weren't
reporting error conditions, so I fixed that too -- which allows the
diseqc code to retry commands on certain temporary failures as Allan
Stirling suggested.
