Yes, I believe this is true. You have enough horsepower to convert the source format to RGB at the required frame rate, however, the speed of the OSD on the PVR-350 is going to create the tearing effect when trying to keep up with the required frame rate of the video. YUV decoding should eliminate the OSD bottleneck, limiting the quality of video playback to that of the processor's ability to convert the source format to YUV and push it out to the YUV buffers at the required frame rate. I think that I have this right. Somebody please steer me back on course if not.
