Disk space is cheap, RAM is expensive. I assume most VDR boxes have 256
MB and less main memory and you need 500 KB per second to hold the data.
Why should I spend 100 EUR extra for more main memory when the disk
space is for free. And even if you use a disk file to store the data the
ram is used for caching. The extra bandwidth necessary can be ignored.
