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. > > This seems to be caused by the second tuner retuning in the > background.

No complete software-fix available. regards, -- Patrick Kernel Labs Inc. http://www.kernellabs.com/
