I had a similar problem with vdr not responding after it had been "idle" for some time. Since I have the PC on all the time this was usually in the mornings. This happened very infrequently between 1 day and 60 days. Checked the log and every time the last vdr entry was something like "Starting EPG scan" so I changed "EPGScanTimeout = 0" and haven't had that problem since then.
