from my fstab
//windows/work /mnt/work smbfs rw,uid=1000 0 0
There are a couple options I don't remember and I'm not at my home computer now. I think using samba is my problem, because I read that smbfs can't handle files over 2GB. (now I can't find that link) From another link that I can't find, I also read that samba has no trouble with writing to NTFS, because samba has it's own file system (or something like that)

Anyway, I just configured the recording program to record to 2GB segments, and I join them when I edit out the commercials in Virtual Dub. It works for now.
