AverTV HD DVR: Problem capturing 1080i video from DVR: audio/video out of sync

[iStorm]

Hi Every one!

I'm in a tough situation currently with my AverTV HD DVR
AverTV HD DVR HDMI 720p/1080i capture card that I need help with if possible..

Here is the deal:

I am currently using an HDCP workaround (you use the AverTV's old driver with VirtualDub).

The thing is that I can capture 720p with ZERO problems through my DVR, but 1080i is giving me a very weird problem.. .

Every single 1080i show that I record is perfectly in sync (audio and video), but by around ~4 minutes in.. the audio starts going out of sync.. I have no idea how to solve this and feel like I have tried EVERYTHING..

I have changed the chunk size/chunks (in Buffer / IO) .. I have used pretty much everything you can think of.. Tried different Hard drives (I have an SSD/WD Cavier Black/Seagate 7200 Barracuda)..

I have tried it on two different computers (my main PC is a Intel i7 980x 6 core and my backup is a AMD Quad Core)..

I have tried different codecs.. etc etc..

I am trying to capture Lossless video/audio and then encode that myself in a program like Megui..

I am pretty experienced in encoding.. but not very experienced in capturing.. but I have read up A LOT and have only had this card for 2 weeks ..

I am using a direct feed of HDMI to my PC from my Uverse DVR.

I also make sure to capture in "No Display" mode so it doesn't put as much stress on the PCI-E.

Please help me with any suggestions you have for audio and video out of sync in 1920x1080 mode .. (this card can only capture up to 1080i)..

I would GREATLY appreciate it guys.. I have tried a ton of other programs as well.. The only one that is remotely good that can do uncompressed video is a program call "AmarecTV," but it is a Japanese program so I can't go to their forums/website to actually diagnose why I am getting dropped frames/inserted frames..

I might also note that I am getting 0 dropped frames/inserted frames in VirtualDub with my change in the buffer/IO settings.

Thanks!!!!
