Hi. I'm facing an occasional ""Communication failure" while tring to burn VOB DVD files. Sometimes the burn proccess is fine, while in other times it fails. I think it fails more if the files are bigger. Here are some details: *Memory: 228M *DMA - on *Nero Burning ROM version: 22.214.171.124 *Burning speed: X4 *TEAK discs. *All other applications on the computer are closed and internet connection is also shut down. *Even the screen saver is disabled. please advise.
