If I play a "good" file, it works just fine anywhere.<br>

I’d be very interested too!<br>
One of my FE is a wireless laptop. Most movies play just fine (including HD), but every now and then is a movie that is always stuttery<br>

I believe the problem is with SD recordings captured using PVR-500 tuners that I'm trying to play back on an HD TV via HDMI on a remote FE. They play successfully on the BE/FE connected to a digital monitor via DVI. ffprobe describes the couple I'm focusing on as:</div><div> Video: mpeg2video (Main), yuv420p(tv, top first), 720x480 [SAR 8:9 DAR 4:3], 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc</div><div> Audio: mp2, 48000 Hz, stereo, s16p, 384 kb/s</div><div><br></div><div>I will try to see what I can come up with to transcode them to MP4 or h.264 and see if that helps.
