Ok, I found that 3 of the programs in my "recorded" database had values of 127 in either
the "bookmark" field or the "cutlist" field. As I recall in earlier versions of
the program these fields were global and contained other values. Possibly
something didn't handle that transition right?

Looking at the code in mainserver.cpp, I can't see why these values were causing
the creation of the programinfos to abort, but the all rows starting with the first one
to have 127 in the tinyint field were not being iterated on.

The work-around weas to patch those values in the sql database so they were "1",
and now the frontend is able to download the recorded list, and most functions seem
to be operating.

On to another matter: Years ago, I added code to my own copy of Mythtv to support
"suggestions" (a la tivo) generated by my program tvwish. I added a column called
"suggested" to record, oldrecorded and recorded, and arranged for the flag to be
copied to the tables at the right time. I put in code so that recordings that
were a suggestion would thus be tagged so that they could be displayed with a
different font in your theme (I made them smaller and darker, but did not just
put them all at the end of the list as Tivo does.)

It's been a while since I did this, and myth has changed, so I am curious -- is this
the best way to do it today? The suggestions are in different program groups so
that is not the way to identify them. I like the smaller darker font, but a little
icon displayed to the side of the entry, or in the status screen could also be appropriate.
I welcome thoughts.

-------------------

Another problem: In the status box, the icons are in two rows. The bottom row displays
stereo, CC and HDTV, and they are always displayed, even on programs that do not have
the HDTV bit set in the recordedprogram table. This is with GANT.

Thanks

I'm sorry I didn't see these posts earlier. If you search the archives I
had the same problem. Removing the bookmark fixed this issue for me as
well.

Is there a bug report? Otherwise others will see this when they upgrade,
and I'll see it again (but know what to do) as there are too many bugs
in trunk right now for me to use it in production and I'm going to
revert. (At least I hope they are bugs, or did they really mean to
change the UI that much?) But the killer bug is that instead of being
better at recording from the 1394 streams, it seems worse. A new kernel
would possibly help, but that's a more one-way change and the new 1394
drivers demand a very recent version, I understand.

I believe this is the original that references the bookmark value. I
chalked it up to some DB error I encountered on my system since it was so
far removed from that revision. Probably something left over from a while
back.

I don't see a link to create an account so I can re-open this one.
Possibly the truncation took place back earlier while I was running
15102, and only started have an bad effect on the more recent
version.

Though looking at the code, I can't see why having 127 in that field causes
the creation of the program list to silently abort, which is its own
bug.

I couldn't find it either. It seemed to happen at the database level when I
was looking which was even stranger. The query.next wouldn't advance
through the results IIRC

Resurecting an old thread, but wanted to let anyone who might stumble
across this to know I've submitted a new ticket:
http://svn.mythtv.org/trac/ticket/7467

I ran into this problem when upgrading from .21-fixes to .22-fixes
(RC2). Turns out I had one recording from 2005 with a value of 127 in
the bookmark column. It rendered my watch recordings list from
populating at all. The workaround (as mentioned) is to manually edit
the value to 1 or 0.

Thanks!

I ran into this issue too.
Would be nice with that one line fix to be added to the schema update code.
It may save other old users the trouble.
