<br>
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>

I am also running combined FE/BE. Also Ubuntu 9.10. I have no issues
at all, so it must be config related. So I am sure we can get your
setup working.<br>
Read only should be fine on /dev/video<br>
