This works well for SD content, I like the improved cutlist creation<br>
logic. But, as with mythcutprojectx, the script fails on HD content<br>
(HDHR tuner). 'mplex' gives about a dozen "++ WARN: [mplex] Stream e0:<br>
data will arrive too late ..." and then "**ERROR: [mplex] Too many<br>
frame<br>
drops -exiting".<br>

Or, of course, it may all be OK apart from remux problems. HD bitrate<br>
too high for the DVD profile.<br>

I see something like this:<br>
<br>
INFO: [mplex] rough-guess multiplexed stream data rate : 4333744<br>
INFO: [mplex] target data-rate specified : 10080000<br>
INFO: [mplex] Setting specified specified data rate: 10080000<br>
<br>
man mplex says:<br>
-r|--mux-bitrate num<br>
The total (non VBR) / peak (VBR) bit-rate of the output stream in k Bits/sec. If unspecified and not set by a preset it is automatically calculated from the input<br>
stream.<br>
<br>
... so it could be worth adding --mux-bitrate 20000<br>
<br>
to the mplex command for an HD recording. No promises.<div><div><br>

</blockquote></div><br></div><div class="gmail_extra" style>Success!! I had to increase --mux-bitrate to 50000 (about 5x the rate estimated by mplex) to get a clean run of mplex on 720p mpeg2 HD content from an HDHR tuner. Will test with 1080i content later today.</div>
