I have a VDR box with three DVB-T tuners.. All cards are saa7146+tda10045 -based budget cards.

I have tried killing VDR when the tuner is jammed, and then try tuning with tzap.. Tuning fails for the "already tuned" channel, but if I simply tune to another transponder and then back, it tunes fine. So apparently the problem is that VDR doesn't even try re-tuning because the tuners are "locked" to specific transponders in channels.conf..
1. So for example using cardX. 2. This card gets tuned to channel C1 by VDR. Once it loses the lock and there is an ongoing recording VDR commits suicide and hopes the problem fixes magically (maybe vdr-launch-script reloads drivers ...) but it does not. 3. You kill VDR and run tzap C1
That also does not lock. But tzap C2 tzap C1 does make it lock.
How should VDR know, it need to lock another frequency first to re-get a lock?
This clearly is a driver/hw bug. And you can only fix it by modifying the driver. So you best report this to the linuxtv-dvb mailinglist and attach more info: exact used hardware, dmesg logs, ...
