Yes. Among many other things. Serious server hardware finally took
care of the problem. I love my 3ware card and tyan serverworks
motherboard.... I can record from all (4) tuners, while realtime
commercial flagging (3) streams, and watching (2) HD frontends and the
primary backend is sitting at less than 10% on each CPU... a little
overkill perhaps, but the consumer-level gear just wasn't cutting it.
