I assume you meant 7454 not 7424.

Good. Your probably seeking in an MPEG-PS container which is expected to work properly although not as fast compared to seeking with a seek table.

Excellent. I've experienced the same. I highly recommend people use this container for their videos if possible.

This is currently expected since MPEG-TS seeking support in FFmpeg has issues which are being worked on upstream. In addition to incorrect behavior it is also painfully slow. Future syncs to FFmpeg will hopefully help with this. 

Please note that any video that doesn't have a seek table built by MythTV will use FFmpeg file based seeking. If you want proper seeking for MPEG-TS files you should build a seek table. The drawback to this is that it can significantly increase the size of your database.

Thanks for taking the time to test and report your results.
