My logs are either owned by hts:hts or hts:video and that doesn't affect the operation of my box (but I'm running the 4.1 branch as I recommend most users should) - I think the hts user should be part of the 'video' group.
If you go into your logs folder and do something like;
cat * | egrep "Some String From Your Video Title"
eg
cat * | egrep "The Late Show"
Do you get any results? If you do get results, do any of them match the exact file(s) that aren't showing in the UI?
Check your user permissions in the TVH webui - if your files are recorded by a different user than you are logged in as then you won't be able to see them.
Check the recordings aren't showing in the 'Failed' tab
