</div></div>A quick google shows a lot of folks having similar problems (not necessarily<br>
with Myth). Some seem to think it's a problem with the 2.6.28 kernel Ubuntu<br>
9.04 is using.<br>
<br>
You might try an SMB/CIFS mount, or even upgrading to 2.6.29.<br>
<br>
Gossamer shows a lot of NFS problems, but I didn't read enough of them to<br>
determine if they are all with 9.04.<br>
<br>
I'm curious what "better tools" would have motivated you to upgrade a working<br>
system.<br>

</font></blockquote></div><br><br>Mythexport 2.0 mostly. That and the fact that I was seeing some writing on the wall that many of the new tools weren't being "backported" to 8.04, only to 8.10. I chose the LTS exactly for the reason you're mentioning, once it works it works for a long while, but with some of the transcoding issues I've had along with the fact that there was some talk about mythexport supporting more than one export feed (I have 4 people with 4 ipods in the house that want 4 different things on their systems) along with the fact that I am a NOTORIOUS ITABFI (If it ain't broke, fix it), along with the fact I get two weeks a year to do any upgrades on the myth system (when my wife and kids are out of town), it all sort of combined to make this my week of upgrades.<br>
<br>Actually, I'm kinda glad to hear it's being blamed on the kernel, that means when the kernel upgrades I can give it a try again and see if it works or not. Till then, looks like I'll try to switch over to a CIFS mount and see if that is more stable.<br>
<br>Thanks for the fast answer...and the virtual smack upside the back of the head for upgrading a working system, I really SHOULD know better.<br><br>--Doug<br>
