Hello, I am using a PVR-150 board, and regularly watch the streams recorded either via the on-board MPEG-2 decoder hardware on my EPIA motherboard or using a standalone DVD player. I have no problems with the picture quality.
However, I recently played some recordings on another DVD player (actually, a HDD/DVD recorder, Hyundai HDVR-5080), and noticed that when there is quick movement, the area of the movement looks very blocky. So blocky, that I suspect the macroblocks are displayed in a completely wrong way. I tried several streams types, 10, 13 and 14 (which is the default I use), and also 0 (PS), but they all exhibit the same problem. The bitrate is not too high (4.8 Mbps, with 6.2 Mbps peak). The same recordings of course play nicely with the EPIA board and the other DVD player, as well as mplayer and other software DVD players. If I re-encode the stream with mencoder (using the lavc encoder, with mpeg2video type) and put it on a DVD, the blockiness also disappears with the Hyundai player. What could be the problem here? Due to the nature of the blockiness I suspect that the motion vectors produced by the PVR board sometimes cannot be decoded properly by the DVD player. Is this possible? If so, can I somehow tell the PVR board to produce different motion vectors? It should be noted, that I use a relatively old version of the ivtv driver, 0.4.5, but I don't think the driver would affect the stream this way. Could it? I also upgraded to the latest firmware downloadable from the Hauppauge site, but the problem remains. Thanks, Istvan _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
