ATI Technologies P/N 137-70268-20 Dropped, Frames during, Requires a fast hard disk system

120 Troubleshooting

Problem

Suggested solution

Dropped	Dropped frames during video recording indicates that
frames during	some part of the system is not fast enough to keep up
video	with the recording. Recording video is a very demanding
recording	task for even the most powerful system. To achieve the
	best results, you must dedicate the PC to recording, and
	ensure that nothing else is active during recording.
	MPEG recording requires a very fast CPU to encode
	the video.
	• Select I Frame Only in the Personal Video Recorder tab
	in Setup.
	• Reduce the frame size of the recording.
	AVI recording creates very large files very quickly,
	and requires a fast hard disk system.
	Try a lower frame size, for example, 320x240. If you do
	not drop frames using 320x240 frame size, but frame
	drops do occur at larger frame sizes, your hard disk may
	not be fast enough.
	• Defragment your hard drive.
	• A large, dedicated disk is recommended if you plan to
	do much video recording.
	• Ensure that DMA is enabled for your hard drive, to
	improve disk access speed and free up the system
	CPU.
	• Close all other running tasks, including those in the
	System Tray — clock, popup reminders, virus
	scanners, etc.
	• Close and exit from any Task Scheduler.
	• Do not log on to your network.
	• Do not connect USB devices while recording.
	• Do not open or close CD-ROM trays while recording.
	• Do not move the mouse while recording.
