Sattech Forum
have a P4 2.8C
3GB PC3200 RAM
160GB SATA
ATI 9550 w/Svideo out (soon will be DVI to my SXGA projector)
Twinhan 102g
MyTheatre latest version (note that one of the previous versions had issues with HDTV)
Onboard audio with optical/coax out
ATI is set to 1024x768 with overscan turned on, SVideo Sharpness maximum
(If you will only be watching SDTV and not HDTV, use 640x480 for a resolution at 60Hz and enable 'Video Mode' in ATI drivers, it'll output a perfect NTSC interlaced signal, but 640x480 is way too low of res for HD content)
(If using DVI, set computer resolution to native resolution of your TV/projector. Another useful tip for MyTheatre, hold left mouse button down and scroll wheel to zoom video this will help crop off noise around edges of channels because DLP/projectors don't overscan.)
In MyTheatre I use Cyberlink (powerdvd) 6 Video Codec and AC3Filter RC5 for audio.
I DO NOT use IVR as I find it softens and brightens the image making it look dull. Also kills CPU in some cases.
I use Generic Renderer.
For SDTV I set cyberlink to Hardware accelerated Bob Mode (make sure you run latest ATI catalyst if applicable it resolved a vertical judder issue)
Bob Mode doubles the framerate so it can display both fields properly, ie. 30fps becomes 60fps. You can't do this on HDTV channels and expect it to work as most are already Progressive and all of them I've seen are already 60fps therefore it would try to do 120fps and mess up because there would be no fields on progessive content. I find Setting to Auto detects and properly selects Bob or weave depending on the content. SDTV is compressed so much that Auto doesn't know what the hell to use. If you want a little bit of reduction in CPU cycles, PowerDVD5/Cyberlink codec also works and uses less CPU. But on some video cards gives blocks and whatnot. There is another codec that seems to work wonders. 'Intervideo Video Decoder for Technotrends' is the name, not sure where I got it, but appears to work better than normal intervideo. No settings, just select it and it seems to automatically display using weave or bob properly between sd and hd content.
For HDTV I set cyberlink to Hardward acceleated Auto Mode
AC3Filter is set to passthrough AC3 to SPDIF, or output 2 channel stereo is not AC3.
Tip: In Task Manager, MyTheatre.exe (the one that has the most CPU usage), Right-click, Priority, Realtime -- This helped out BIG time!
I have my timeshift buffer set to file 2048MB Use OS Cache IS enabled (such a huuuuuge help with hard drive performance). (I'll be increasing size as 2048 is only about 20 mins in HD mode. For best results, a 2nd hard drive for timeshift only is optimal... if you'll be recording anyways, just watching live tv it won't do much.) for some reason memory buffer can't go above about 1.4GB I think it's a windows issue with how much a single program can allocate.
My Record speed is 10X but some people report lower record speeds help.
I have 7% CPU usage on SDTV, and 15% to 25% usage on HDTV.
I use Girder with a MCE Remote plugin to control the works and DVBEPG for my program guide.
