[QUOTE="archive10, post: 761200"] But back to the topic: Software in such boxes are generally event driven. I could suspect that errors in the lock-on, demuxing or decoding could trigger an interrupt to the middleware. This would for example be an interrupt from the hardware telling the software of decoding errors, triggering the "bad or no signal" box being displayed. Now if some part of the software was not designed to cope with continous on-slaught of events or interrupts that an almost legible, but severely degraded signal, might create; you can have stack-overflows, memory exhausts or similar things bringing things to a halt. That could take out the UI handling process, while still leaving the "automated" parts (decoding, HDD recording) still running in the background. This is what leads me to speculate that it's the application software which isn't coping with the situation. [/QUOTE]
