Hi, Same Camcorder as me.... good choice
The problem you are describing is a fault of your PC. 10 Minutes or so sounds to me like you are capturing at DV quality, producing 178MB every minute (ish) just after 10 minutes your PC throws a wobbly about file size...which by then is probably 3.99GB or ther abouts? does this sound right.
On PCs there are more than one type of file system format. If you are using FAT32 it cannot create a file larger than 4GB. The solution is to use the file system NTFS, then you can create any size of file. If you tell me what OS you have ...XP Win2K etc I may be able to help. There is an instruction to type into "Run" which changes the file system. If you have to change you main drive where the OS is you may have difficulty. It is usally reliable and save(i know loads of people that have done it, but it is at your own risk.
Cheers,
Duncan
