(Actually, I just trawled up an excellent article at http://www.hometheaterhifi.com/volume_7_4/dvd-benchmark-part-5-progressive-1 0-2000.html) So taking this and your recent reply to Billy... In my case I would decode two consecutive wavelet images into an odd and even field, weave them into a 704x486 image, copy it to shm, then call XvShmPutImage twice, setting the XvPortAttribute appropriately. If I lose phase, say I get two even fields in a row, then should I weave two frames with anything on the odd scan lines andcall XvShmPutImage once for each frame with the PortAttribute set for an the field each time? -- Paul _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
