Recently, I updated my capture partition to NTFS due to a hdd upgrade. When I'm using any kind of WDM related software, e.g. iuVCR & FlyDS, the A/V sync increases with the length of the capture. Lets say the latency is 0 ms at time 00:00:00. When I finished the capture and played the file, the latency steadily increases. At 7:00:00, it was almost 2000 ms!
I used all available sync options in iuVCR: Sync by stream offset, use system timer for both audio and video streams, master stream is the audio. Didn't help a bit. This didn't occur when I used FAT32 and segmented capture.
I'm also getting evenly framedrops with both FAT32 and NTFS, about 1 frame every 90 seconds. I first thought this was the cause for my snyc problem, but as I wrote, I had no such sync problems with FAT32.
It also isn't a too high datarate(1200 kb/sec) or too much CPU utilisation(60%).
I'd appreciate any solution!
