[QUOTE="ltb76, post: 835866, member: 85849"] Hi, I have my TV server running just fine under ESXi 5 with no stutter. My hardware is as follows: Motherboard: Asrock Fatal1ty Z68 Professional Gen3 16GB RAM CPU Intel i7-2600 LSI 9265-8i MegaRaid 8x Western Digital 7200rpm 2TB disks for VMs (7 running RAID 5, 1 hot-spare. connected to the LSI card) TV Card: 1x Digital Devices Octopus, 2x DuoFlex CT v2 (dual DVB-C), 1x DD Common Interface 1x Kingston 128GB SSD 2x Western Digital 7200rpm 500GB 2.5” connected directly to an onboard controller. My TV server VM is based on Win7 pro 32bit. I have allocated 1GB RAM and 2 CPUs to it. The system-drive is located on the LSI RAID, a 2GB drive dedicated for SWAP located on the SSD (Not really used though), a 8GB drive dedicated to time shifting also located on the SSD. 1 onboard SATA controller is passed through to the TV Server VM, and the 2x 500GB disks are running RAID0, this drive is used for recordings by both dual DVB-C Tuners. And obviously the Digital Devices Octopus card is passed through to the VM. Initially I just did recordings to a virtual disk on the LSI RAID. But heavy load from other VMs on the LSI RAID could in rare cases give a few artifacts / lock ups in recordings. I’m not running the frontend as a VM. Pass-through of the video card was a bit tricky. I could not get my nVidia card to work. It worked with an old Matrox card, but that was not power full enough for 1080p I have read that the nVidia cards should be notorious bad for VT-d, apparently ATI cards should be better for this. I have tried with USB tuners (Terratec and Hauppauge) that did not work well. I had a lot of stutters, lockups and BSOD on the TV Server. However I have found the Terratec tuners to be performing poorly even on my desktop PC. In regards to the NIC. I have a dual Intel gigabit card teamed, this is shared between all my LAN VMs. I have not a dedicated card for the TV Server, that does not seem to be necessary. The trick in getting this to work is getting the right hardware. Even though manufactures claim their motherboards are VT-d compatible I have found it to be faulty on several boards. And make sure to get a CPU that supports it, stay clear of the “K” CPUs. I'm guessing that the HP N40L is no way near powerful enough for this. Especially the disk controller would be an issue, and that is probably why you have the stuttering. Cheers [/QUOTE]
