Do you encode and decode on a 350 simultaneously via NFS? Unfortunately, I can't try a new NIC. It's on-board and the only PCI slot in my Shuttle takes the PVR350. I haven't seen a NIC go bad like this before - it's more likely that it has a small on-chip RX buffer and there's too much going on in kernel-space for it to process all inbound traffic. I've seen TX errors too but they are less common. The box recorded an hour overnight with no further dropped packets, so simply encoding to NFS may not trigger this. I'll check to see what type of activity actually causes it. It may be that overruns only occur when doing encode/decode over NFS at the same time... FWIW, the NFS server is a 1GHz PIII (with a DVB card in it) and it doesn't accrue NIC errors.
