Ulead DVD MF Capture - Why is it stopping at 30 minutes?

[MrMungus]

I'm capturing videotape and have the "Quality" setting at 15 which means, I guess, that the frames go into a buffer and the that data is written to the hard drive from the buffer (since there's a DV buffer transcoding step when I stop encoding). Anyway, I'm trying to capture two hours of video but the program keeps stopping at 36 minutes or so then writes out the contents of the buffer to the hard drive. Anybody else experience this? Is there a buffer limit?

For those who are capturing directly to the MPEG file format using OHCI compliant IEEE 1394 (FIREWIRE) PCI capture cards, Ulead employs a TRANSCODE BUFFER.

This transcode buffer is designed prevent any frame-dropping on computer systems with slower processors.

Please be advised the setting of "15" isn't necessary for video with most types of motion.

The quality setting affects the motion estimation algorithm of the Ulead MPEG.Now codec, which is based on the MainConcept SDK.

For video with the most common types of motion, a setting of "8" will deliver very good quality.

High settings greatly increase the load on your system processor.

In addition, high settings can yield no visible quality improvement.

Reserve high settings for those video clips with unusual motion content.

The direct capture to MPEG feature is processor intensive because the CPU must transcode the incoming DV stream in real time.

Footnote:

To allow users to enjoy the benefits of large .avi file support, Ulead capture tools support Microsoft's Direct Show media architecture.

Those who use OHCI compliant IEEE 1394 (FIREWIRE) PCI capture cards on Windows 2000/XP systems with NTFS formatted hard drives can take full advantage of the large .avi file size capture support.

Those who use capture devices that still operate in the older Microsoft VIDEO-FOR-WINDOWS media architecture (also supported by Ulead) will not be able to enjoy large .avi file capture support.

As you may already know, support for large .avi file sizes requires NTFS formatted hard drives on Windows 2000/XP systems.

I'm confused. Is there a benefit to using a 15 setting or not? Your reply is contradictary.

I thought maybe the benefit was that the frames, since they go into a buffer instead of directly to the hard drive, are processed more thoroughly since there's more time to process the frames (thus, a higher quality level than if you use a lower setting). When I use a quality level of 8, I get *no* transcoding step.
