[vdr] Tuning failures for transponder-locked tuners (VDR 1.4.7)

Teemu,

I had a similar problem with budget Freecom / WT-220U USB stick tuners.
I usually had to swap multiplex/transponder to get them to re-tune reliably.
I observed that if they lost tuning, vdr made them re-try (which I saw in the log)
but eventually would bomb out if it couldn't tune, which is maybe what you're seeing?

Originally I logged it as a DVB driver bug, but the maintainer said it was an application bug.

I found the following, which requires you to patch/rebuild vdr from source.
Basically it just adds a small delay to the tuning process, and it works 100% for me.

I had to do this on 1.4.7 and carried it over in 1.6.0 also - so no, vanilla 1.6 won't help you.

It would be good if something equivalent was in vanilla VDR but I suppose it slows 
some systems by a fraction of a second when tuning.  
Perhaps a  "budget card" option?
