Using KnoppMyth (Thanks Cecil!), and upgraded to 0.19 last night.
Apart from having some issues getting my 350's IR receiver to work
(still unresolved, any hints?), things went great. I noticed today
that when a recording is due, it actually appears to launch twice. File size for the second iteration shows up as 'B' in Mythweb. In 'recorded programs', there is no thumbnail.

Here's an example that just occured. (It's for my wife, no Oprah
comments please ! )

on cardid 1, sourceid 1


I then see (2) entries in the recorded programs (and mythweb) view.
Resulting entry in logs are:

I've only got (1) cardid in the cardinput table, so I don't think this
is the issue.

Any hints on where I need to look next ?

Thanks,
Greg.
