Have you tried playing these files with VLC or similar? I'm pretty sure that it is a corrupt BTV configuration file. You mention that some shows play, are they in the same folder? Is there a correlation between the recorded date and whether they will play. Try deleting your default recordings folder in web admin and create a new default folder. Then see if it records and plays. If it does, you can reset the original folder as your default or move the files to the new folder in Windows explorer.

I seem to remember that I solved a similar/same problem by deleting one of the BTV configuration files (can't remember which one).
