I used to get drop outs at a rate of about one per hour and now the TV has been on for 24 hours straight without a problem. I'm quite confident to say that downgrading to the september drivers solved the problem. I hope that's a hint to the developers, so that they can look into what parts of the code they've changed since september...
You 're right i have the same problem after update drivers to 5.10.2009 until now 23.12.2009 drivers and 24.12.2009 enigma.Older versions its ok.Hope someone fix this.
