It has degenerated to extremely jerky video and sound far out of synch. In short a mess.
Having done some research on the subject I see XP in its wisdom resets DMA input/ output to PIO, without of course XP saying anything. Much less giving any helpful tips about streaming video.
My understanding of streaming video is data received from video streaming source is basically, switch buffers and squirt it out through the graphics processor and display on screen plus sound through sound processor.
i.e. no clever transformations requiring large amounts of graphics processing e.g. as in rotations etc on 3D draughting packages.
So my thoughts are that XP is / has changed DMA I/O to cripplingly slow PIO I/O, hence dismal video display as a series of 'stills' and even picture break up into squares, with sound miles out of sync and even 'splashy' break up of sound.
I did some cleaning up of software on my system via Control Panel and Add/ Remove software, to see if it removed any system overhead. Anything that said 'rarely used' got deleted. It did seem to make a slight improvement -- for a short time (few days)-- then back to square one again.
I don't do anything else using graphics other than edit pictures from my Canon Power Shot A580 very basic digital camera. I did have to reload .Netframe3.5 to get my Canon picture editing suit (Zoom Browser EX) to work.
Can anyone confirm / otherwise if DMA is reset to PIO and is affecting video streaming? If it is how do I set back to DMA again? But in any case help me out of the treacle swamp I seem to be stuck in with video.
Perhaps I should add I run Open Office 4.0.1 but everything else is plain vanilla Bill Gates ware.
