Thanks, Niklas, Steve and Nick for responding. Nice to actually get some feedback on the mythtv-users list :)

MPEG record specifications: * NTSC format at 29.97fps: Full D1: 720x480, MPEG1: 352x240 * PAL format at 25fps: Full D1: 720x576, MPEG1: 352x288 MPEG hardware player specifications: * NTSC output: Full D1: 720x480, MPEG1: 352x240 * PAL output: Full D1: 720x576, MPEG1: 352x288 ...are misleading with all the previous usage of the term "MPEG2" in the same document. A quick primer in their specs on "D1" would have been helpful. e.g.: this entry from DigitalFaq.com... D-Values. Various resolutions are often referred to as D-values. Full D1 video is 720x480. Cropped D1 is 704x480. Half D1 video is 352x480. Quarter D1 (actually SIF) video is 352x240. Two-Thirds D1 video is 480x480. DVB and DVD-VR use unusual MPEG resolutions, sometimes called Three-Fourths D1 at 544x480. re: quality issues, I found that tweaking the brightness, color, and contrast via ivtvctl did help improve the look of the 350's tv-out quite a bit. A quick run through some MySQL commands and I had my channel appearance preferences installed across the entire range. I did my best to match them up visually to my Avia-tuned Sony, just eyeballing it and switching back endlessly between TV and Video1 :) Thanks again! -Matt -- -------------------------------------------------------------------------
