Hi rross,
Thanks for explaining the issue further. When you say that the files are not being read as recorded at 60p, are you getting error messages when selecting the 60p option when creating the discs? I suggest uninstalling the program and downloading the latest version of PlayMemories Home to resolve the issue.
NOTE: I have fixed the link to the guide to creating the Bluray discs.
If my post answers your question, please mark it as "Accept as Solution". Thanks_Mitch
