I've been seeing this problem as well as the freeze on transition
issue for the last month so. The freeze on transition is very
consistent, however the problem of not creating a new file on
transistion is very intermittant and has caused quite a problem as it
has created files over 30GB when LiveTV was left on over night,
resulting in the system running out of disk space and crashing myth.
There were a mix of non-expirable shows, expirable shows and LiveTV
plus the slave backend OS on a 120GB drive - so once the
auto-expirable shows were deleted it couldn't delete anything else.

So I don't think that the issue you found is due to Shane's patch
since I've been seeing it for a while as well. I hope to try his patch
this weekend as the entire family appreciation factor has gone down
with the LiveTV freezes.
