Hey everyone, I have my played around with my SA 8300 DVR and I was able to get good, not great captures on my PC. Here is how I did it. Step-by-step. (I can't post links yet.)
I first followed the directions listed on AVS forum for recording by IEEE 1394. With one exception. I am using the Vista drivers. Vista drivers improved performance slightly. You can get the Vista drivers on Timmorre's sight. Google "firestb.msi" for the drivers. Note: Vista drivers are 32-bit only. Not a problem for most people since pre-installs are always 32-bit (though they should be 64-bit because the 32-bit Vista is crippled a little).
I used the latest version of VLC to capture. Although, I was successful in getting other programs to capture.
I turned caching values to 0 in the advanced DirectShow properties in the options for capture. The sound is jittery during playback, but that is not how it is capturing. I find caching values of 0 improve the video capture, decreasing errors. I also find that the video has less errors in Vista. And finally, I find 720p video to have less errors too.
Note, I still haven't obtained perfect capture. But if I keep tweaking and keep playing, I may yet. Hope this helps.
I currently have the latest firmware for my 8300. You know you have it if it can fast forward by 4x. My cable company is Suddenlink in North Carolina.
P.S. Can someone post the correct links?
