In the VDR-ML-thread you said that you have 2 of those devices?

I could get my hands on the information which is date 3-4 years ago when the 
device was designed and in fact the problem you're describing existed at 
that time. It was fixed by hardware and normally should not appear in end-
user's products. However as I understand the fix can easily fail if the 
production-site a) does not  know that this problem exists and thus does not 
test it or b) doesn't care. Rumors say, that the prod-site has been 
transferred from France to China. If that is true or if your device is 
simply a runner or anything else is not clear as of now.

When did you purchase this device? If it was recently, there is a fair 
chance that exchanging it will result in a working device.

Most likely. No complete software-fix available.
