I was all psyched up to answer your question but you didn't ask one.
So is this just a complaint that you're not going to lift a finger
to do anything about and just brow beat the people who spent hundreds
of man hours creating what you have so far that you downloaded for free?
Joseph, you should know better. I'll try to answer the questions you
should have asked.

Is anything being done to track failed recordings on oldrecorded?
Yes. One of the biggest invisible changes between 18 and 19 is that
there were a lot of changes related to how we keep track of shows
during their airtime, what is stored in oldrecorded and how that
can be reused, what happens when master and slave backends restart
and it all leads to the ability to change the end time of recordings
in progress. Part of this is a new state rsAborted to mark a failed
recordings to make you aware of the problem, allow reactivate, allow
re-record and display this info after the fact on the Previously
Recorded page. This state is set certainly for a backend crash and
should be incorporated for other recording failures that can be detected.

Do I have to cower like a little girl and use SVN from before the live
TV changes? [You would have been better off phrasing this for yourself.]
No. It's been working just fine for quite a while. There are rough
spots to smooth out like anything else but the last major piece, the
transition from live to scheduled recording, went in this week. A lot
of other fixes have gone in in the meantime possibly related to the
issues you had above. Current SVN is in much better shape than 7569.

How can I fix the oldrecorded entries for these shows that didn't
record? If you'd found the problem from trying to play the recordings
from the Watch Recordings page, I would hope that you chose the
allow re-record option (duh =). Generic showings aren't supposed to
have this button but this doesn't always work out right. You can
always go to the Previously Recorded page. Sort by time may help
cluster the shows in question. The 'Enter' key shows buttons to
delete the one entry or all entries for that title. Also, on the list,
"D" is a shortcut to delete the one highlighted item. If you're not
sure of which shows were affected, go through your backend to find
the times and channels when you had this problem. If you use "-v record"
you would see the titles also.
