I just built a HTPC and having trouble with video playback:
1. Blu-Ray and DVD video stutters with Total Media Theatre 5
2. Blu-Ray/DVD works perfectly with PowerDVD 11.
3. Online video streaming via Netflix or Youtube stutters, tried to switch between HD and non-HD, still the same result.

I have the following hardware running Windows 7 64-bit Home Premium:

1. AMD FX 4100 3.6GHZ quad core
2. Asus M5A97 motherboard
3. Sapphire Radeon HD 6570 1 GB DDR3 connected to a Epson 6500UB projector via Denon 2809CI receiver.
4. Corsair XMS3 4 GB 1333MHz PC3-10666 240-pin DDR3
5. Western Digital Caviar Green 2 TB Desktop Hard Drive WD20EARX
6. LG BH12LS38 blu-ray burner
7. Lite-On DVD burner
8. Antec EA-380D Power Supply EA-380D
9. SilverStone LC13B-E HTPC Case
  • I have installed the latest graphics drivers from AMD website and latest motherboard drivers from Asus website.
  • I have installed the latest silverlight and flash player for both IE and Firefox.
  • I turned off all video enhancement settings in Radeon control panel, but the results were the same.

I know that Radeon 6570 is not yet fully supported by TMT, but why is the online video playback so choppy? I also disabled the hardware acceleration in Silverlight and Flash, still the same issue.

Any ideas guys?

Turns out that the display device was set to 1080p/24Hz. I changed it to 1080p/60Hz and viola...Blu-Ray in TMT5 is now perfect and Youtube is smooth. Netflix has slight stutter, but is viewable.

I am guessing unless a new silverlight version fixes these issues or Netflix does something about it, this is all I can do about it.

I understand that 1080p24Hz -> 1080p60Hz is a 2:3 pulldown and that is not recommended for Blu-Rays. But with my current setup, I need to play DVDs, Netflix, youtube in addition to Blu-Rays, so there is no easy way to switch between 24Hz<->60Hz based on usage. Is there a way to workaround this?

MediaPortal has a "refresh rate changer" in its configuration where you specify the rate based on identifiers it reads from MediaInfo when it opens the file. It just switched between 60 and 24 as it needs.

If you know what you need and trigger it before entering the program, you could make separate profiles on your video card (1080p/60 & 1080p/24) and switch between them with a hotkey.

What are your driver settings? Turn everything off but deinterlacing and see how that behaves.

Thanks, will try that for sure.

I tried it, Blu Ray works that way, but everything else (DVD, online video streaming) stutters and tears real bad.

Currently, I am on these settings and everything seems to be working fine:
1. Default settings in Radeon control panel, with refresh rate set to 60Hz.
2. Denon receiver: Turned off upconversion for HDMI video
3. Projector: Turned off 4:4 pulldown and turned off Frame interpolation
4. Disabled 60Hz-<24Hz conversion in TMT5.
