Thanks Mark for both your suggestions. I'm prettuy sure the Motorola is set up properly, using 720p as the output format, and outputting the original format. The only difference being that I'm currently outputting sound over s/pdiff (Ill try RCA during testing tho.<BR>
<BR>
The /dev/video0 permissions I haven't checked. Good point! Do I need r or rw permissions from the mythtv group?<BR>
<BR>
Will try again this evening, as I only had a few seconds yetserday before family took over the tv. Will also look more closely at frontend log, and dmesg. <BR>
<BR>
System is combined BE/FE and 64 bit btw.<BR>
<BR>
Cheers!<BR>
