I just replaced my PVR350 with a pair of AVerTVHD MCE A180s in preparation for the HDTV deadline. Yes, I use an antenna - no cable here. Having two cards is great as I can record more than one program at a time. I had very few problems with their install, thanks to this forum. They are working perfectly.<br>
<br>My front-end units on a couple of the televisions in the house are Hauppauge MediaMVPs. I've used the mvpmc distro for a couple of years now without any issues. However, these units can't process the 1920x1080 mpeg2 stream (not to mention network bandwidth issues). So I need to transcode the recordings.<br>
<br>I can't seem to get a good read on what to use and the paramters for the various programs. I have tried both mencoder and ffmpeg.<br><br>The first thing I do is check to see what resolution the recording is by doing<br>
<br>$w = `mplayer -nosound -vo null -ss 03:00:00 -really-quiet -identify $F1 2>/dev/null | grep ID_VIDEO_WIDTH`;<br><br>in a perl script. If the width is less than 720, the the MediaMVPs seem to work fine and no transcoding is necessary. However if it's greater than 720 I transcode with ffmpeg <br>
<br>ffmpeg -i $F1 -croptop 12 -target ntsc-dvd $F2<br><br>I needed to add the croptop because there is some noise that I get in the recording (don't know why).<br><br>Anyway, with ffmpeg I have noticed some voice sync problems with the MediaMVP. The picture looks fine. Playback on a PC using either the ASX stream from MythWeb or using MythTVPlayer on widows is fine.<br>
<br>Appreciate any advise available for a better transcoding method!!!<br><br><br><br><br><br><br><br>
