Hardware:
  • CPU: Intel Core 2 E8400 2.8Ghz (stock cooler)
  • Motherboard: GIGABYTE GA-E7AUM-DS2H
  • Memory: A-DATA ADQVE1A16K DDR2-800 2 x 1GB
  • Graphics Card: Built-in GeForce 9400
  • HDD: Western Digital WD6400AAKS 640GB SATA 3.0Gbps
  • PSU: Corsair VX450W CMPSU-450VX
  • Case: Antec Fusion Remote Black
  • Other: Hauppage HVR-2250
  • TV: Sony 40" LCD (KDL-40W4100) connected to HTPC via HDMI
Software:
  • Windows XP SP3 (no post SP3 updates)
  • .Net 3.5 SP1 plus hotfixes
  • GPBVR
  • Windows Media Player
  • InterVideo Codecs
  • PowerDVD 9 Codecs

I've spent two weeks trying everything I can think of, and still cannot get the GeForce 9400 IGP to play MPEG-2 without stuttering. When playing Live TV it stutters on all channels, although some are worse than others. When playing DVDs it stutters, but is not near as bad as Live TV. The CPU occasionally spikes to 50%, but usually hovers around 10%.

Here is what I've tried so far (at least what I can remember):
  • Tried built-in Windows MPEG-2 codec
  • Tried CyberLink PowerDVD 9 codec
  • Tried InterVideo codec (ships with Hauppage HVR-2250)
  • Played Live TV in GBPVR, tweaking anything I could think of
  • Played DVDs in Windows Media Player 10
  • Moved the HVR-2250 card from the PCIe x1 to the PCIe x16 slot
  • A thousand other tweaks I can't remember right now
  • BIOS
    • Disabled serial and parallel
    • Increased shared video memory to 512M
  • NVidia Control Panel
    • Changed output to 1080p@60Hz
    • Changed output to 1080i@60Hz and 24Hz
    • Enabled & disabled Inverse Telecine (with 1080p & 1080i)
    • Enabled & disabled Force VSync (with 1080p & 1080i)
I would greatly appreciate any help as I'm about ready to return the board.

Does your audio also stutter? If yes then make sure that the dirvers for your audio card as well as for you sytem BIOS are also current.

I am not sure if you have also tried outputting 1080i or 720p to your display instead of 1080p/60. If not I suggest that you try then both.

My PCI-e GeForce 9400 GT cards work perfectly with vista media center HD recordings. No stutter at all (only VERY occasional reception glitches occur). Using 2.2 and 2.5 GHz AMD 64 X2 CPUs in various MSI K9 series mother boards. Outputting 1080p. Recording 720p and 1080i as broadcast.
Latest NVIDIA drivers but Realtek HD audio drivers from MoBo CDs. I'm interested in the resolution of all of this. I expected these 9400 IGP cards to be great.

Edit: Hauppauge 1600 tuners (PCI). 2 in each system.

Been there, done that. Was not impressed with the board in XP SP3. Works great in Vista, but I had the same issues you did with minor stutters. walford's suggestion to try different audio codecs is a good one, as that is often a source of video problems (as counter-intuitive as that seems). I never resolved it for standard-def interlaced sources or for high-def progressive sources. It appeared to be something in the VMR9 renderer. Sorry to be the bearer of bad tidings.

I do not speak officially in any sense for
Intel Corp., Technology Manufacturing Group
but I do work there.

Trying different audio codecs are definitely worth a try.

Thanks for the suggestions. As far as codecs are concerned, I tried CyberLink, InterVideo NonCSS (came with HVR-2250) and ffdshow. They all exhibited identical behavior. I wish I would have known it was an XP/VMR9 issue before I started this whole process as it would have saved me a TON of time.

Thanks for all the suggestions. I appreciate you taking the time to reply. To keep the wife happy I returned most of the hardware to NewEgg this morning and will just go with Tivo.

NewEgg would not all me to return the CPU because I'm outside the 7-day return period so I have an Intel E8400 I'll part with for $100 if anyone is interested. If not it's going on Craig's list.
