Thanks for sharing. You've been adding some good documents to the forum recently. Much appreciated.
Cirrus was probably the second-worst chipset of its day, because it was competing with Zoran, LSI Logic, Pioneer-Renesas, and a few others. The only worse chipset was the in-house Panasonic chips used on the "E" (pre-ES) series machines. Cirrus was found in the cheap off-brand DVD recorders from companies like Cyberhome.
In the grand scheme of things Cirrus was an average encoder chip best used at 2-hour SP mode, and nothing else. And only when the video source materials were clean, like DV camera, analog TV (cable, OTA, satellite), and maybe 8mm/Hi8 (which is not noisy like VHS). A lot of Cirrus recorders used CBR encoding, which really looked bad.
I would not purposely used a Cirrus recorder.
I need to update this article ASAP:
