I would guess that HD throughput is the issue as well. TS files take a major chunk of a hard drive's bandwidth. I suggest putting Windows on one drive and recordings on another (physical drive, not just partition.) Also, make sure that background processes, such as virus scanners or disk indexing, are set to not access the drive used for MP recordings. You might want to look at a fast SATA2 drive, such as the Western Digital Black series, for recordings. Throughput can also sometimes be improved with a better SATA controller or by tuning/troubleshooting the SATA disk drivers. Some nVidia SATA drivers have performance issues. The Windows drivers are usually best.
The CPU could be an issue if the hard drive controller uses a lot of CPU to do its job and the CPU is heavily loaded. This is typical of on board controllers or cheap SATA cards. PCI/PCIe bus throughput can also be an issue if video bandwidth is high. That could be solved with a better/faster motherboard and CPU. In my experience, CPU speed is not an issue on a dedicated MP server.
BTW, HD-PVR is still working well here. Garry
