Hi!
I use NAS system to store VDR data.  Speed of network between HTPC and NAS is 
over 700 Mbit/s. However reading and writing to RAID5 is only 20MB/s at peak 
and about 10MB/s average.
Normally everything is fine, but when there is one or more noad running, 
reading/writing data to that same NAS. I start to get those 
Oct 18 13:13:33 htpc vdr: [11827] ERROR: 610 ring buffer overflows (114557 
bytes dropped)
Oct 18 13:13:36 htpc vdr: [11827] ERROR: 15292 ring buffer overflows (2874896 
bytes dropped)
Oct 18 13:13:37 htpc vdr: [11827] ERROR: 10946 ring buffer overflows (2057848 
bytes dropped)
Oct 18 13:13:37 htpc vdr: [11827] ERROR: 14786 ring buffer overflows (2779768 
bytes dropped)


OK, I can stop using noad... But is there way to allocate "enought" memory to 
ring buffer, so it would not suffer when noad is running?!?  My machine have 
3 Gigs of memory, so I could "allocate" even 1 Gig to that ring buffer.
