Changing Hardware acceleration to 'None' = jerky video

[jonas more]

I have been using Replay Screencast screen capture software for the past few months without any problems... until recently.

To use the program I have always had to change my Hardware Acceleration setting to 'None' to avoid recording a black screen.

Recently every time I change my Hardware Acceleration setting to 'None', any video I play on my computer (regardelss of player) becomes jerky... even if I haven't opened Replay Screencast.

I use Windows XP.

Does anyone know what would cause this problem?

Most user's play a video file in default player which use's directdraw acceleration ... then play the one the want in another ... disable audio in first .

A program that require's you to keep messing with hardware acceleration , is just messing about , and more likely to cause system problem's sooner or later ... consider downloading this free one from : http://www.zdsoft.com/ ... easy to setup and use .

But apart from this ... from your computer listed hardware ... it will serverly stuggle ... seriously .

For more advanced system's with tv out ...

Video + audio out to vcr
Vcr record's info to high quality tape
Pc record's vcr playback later via high quality recording device ... mine's avertv usb2 under xp .

It's how I record all my game's ...

Thanks!

I had NO idea that repeatedly setting Hardware Acceleration to None could cause system problems.

It was what was suggested in the Replay Screencast User Guide but if doing so can cause other problems... what's the point?

Thanks again and I'll give the program you suggested a try.

As far as I know, when you disable hardware acceleration, the video card doesn't use the overlay mixer to display video (if it does, you get a black screen when capturing a screenshot). Try using another player (like media player classic) and use VMR7/9 as the renderer for video, or if you use windows media player, use the high quality mode on advanced options (use both with hardware accel.; no need to disable it).

In the graphics card's setup applet look for a setting called "write combining". If it's disabled, enable it. That might help.

It could be that you changed upgraded or had updated codecs. Some of them are better about non accerlerated video rendering then others (i.e. requiring less or more steps). (Also sometimes they are the same but an update gives you weird loops filter loops like huffyuv decoder to huffyuv encoder to huffyuv decoder). You might want to see how some files render in graphedit. There is nothing wrong with turning off video acceleration repeatedly or not it just can sometimes expose you to things you wouldn't see otherwise.
