Large Recording Stutter

[Goodspike]

The only problem I have with SageTV is that for very long recordings, I get video studder once a program I'm recording is over about two hours long, but only if I watch it while I'm recording it. If I watch it after I'm done recording, it's fine. If I change the channel while it's recording, which forces Sage to start a new file, I can switch the channel back and watch either portion (old file or new file) fine while it continues to record. I view it as an NTFS issue because if I wasn't using NFTS, Sage would limit the file size.

I just changed the media drive out on my HTPC. In doing so I went from PATA to SATA, and thus I am using obviously not only a new interface, but also a new driver. And since it only happens when the file is large, I think that pretty well rules out any issues pertaining to the video card, etc.

So, does anyone know of anything I can do? I'm thinking if I could get XP to not check if it's writing to a valid cluster, or get Sage or XP to limit the file size allowed on NTFS, that might help, but I have no idea if that's possible. Would the overhead of writing to drive be reduced if I went to a mirroring RAID setup (I can never remember the numbers, but I think I mean RAID 1--where both discs are identical)? I don't really need that safety with media, but if it will get rid of the issue I'd be more than happy to pop for a second identical drive. Other ideas?

BTW, the drivers were both formatted with 64k clusters, and it's a 3.0+ Athlon 64 machine with an A8V Deluxe motherboard. I've been following stutter issues here for a while, and tried I think every potential fix (e.g AGP aperture, etc.)
