That would be good to know. If you find an old snapshot without the problem, I 
would be really pleased to know!

Next time it happens, could you try unloading _all_ the drivers and reloading 
them... I mean including things like dvb-core. I know that reloading the 
frontend/card driver doesn't help, but I'd like to know for sure that 
reloading all DVB related stuff doesn't as well.

Yup, that seems to be what everyone else sees. Only the budget cards break. 
OK: so its definitely not a frontend bug.

As for updating VDR causing it - it may indeed be something VDR now does a bit 
differently which makes it happen more often... but VDR isn't at fault here 
IMO.

Could something in the saa7146 be being tripped up somehow so that a poweron 
reset is needed to fix it?

Does anyone use VDR with a twinhan or other non-saa7146-based budget card for 
EPG? And does it have this problem?
