[QUOTE=hardya;2561981]I can only change for MPEG2. MPEG2 DXVA is supported, other changse are not supported by the graphics card. For my example of converting FROM MPEG2 (*.ts, *.mpg) TO WMV, I guess it would need to be that the problem was at the reading end rather than the writing end. What do you think?
[B]I presume I can still leave “DirectShow” in use. What about the audio and video Directshow filters?[/B] [/QUOTE]
DirectShow and the DirectShow filter is related to the “Preview” window playback not the conversion process, the settings I’m referring to is in common settings-> [B]A/V Codec[/B].
Since doing conversions take a lot of CPU usage/resources you should close all programs that are running in the background and don’t use the system during the conversion process, and on the A/V Codec settings page choose “Software” for all the settings.
I don’t know what brand or model your graphic card is but you may also want to check to make sure the graphic card driver is up to date.
