[QUOTE="ajp8164, post: 736806, member: 64375"] Hi All, I've had a chance to look into the a/v sync issue with my directv-hdpvr on Win7 setup. I haven't looked at the setup in any real detail in quite a while and I have found that it appears my system is not using hardware acceleration to render the stream(!) My CPU use is 75%+ when using MP. So, I backed up to the Arcsoft TME software to monitor the CPU use with it, and with TME my CPU use is around 15% (!) I'm not sure what's going on here. I moved to Win7 from WinXP several months ago and I suppose it's been using a software renderer since. Here are the basics of my setup: [LIST] [*]Stream is 1280x720p [*].Net framework 4 (doesn't look like I have .Net 3; do I need explicitly?) [*]ArcSoft video and audio encoders [*]TV renderer set to EVR [*]HD3200 onboard with 512Mb allocated [/LIST] I used GraphStudio to check the graph and it shows a Line 21 filter feeding EVR. Anyone know what this is? I tried to backup to VMR9 but it made no difference. What's going on here? [/QUOTE]
