Have recently upgtaded my Redeon Graphics card due to it becoming faulty to a Geforce 650TI card but now when I try to playback to view files in the
Project timeline viewscreen it runs a couple of seconds then hangs while a little window underneath it opens showing a status bar and sayingi "Rendering". The playback then runs another couple of seconds then the same thing repeats continuously.
Any editing is out of the question as it is impossible to playback and view files.
Does anyone have any views on this?
Thanks
paul
