Bug description:
I had previously been running a beta of mythbuntu 9.10 and everything was working fine. once the RC build was available, I did a dist-upgrade to the most recent packages. since that point in time, trying to rip a dvd fails to connect to the transcoder. checking dmesg, I see output along the following lines:

[  469.781725] mtd[2295]: segfault at 10000 ip 08071258 sp b6801920 error 4 in mtd[8048000+4a000]

I don't see any problems in /var/log/mythtv/mtd.log.
