Daniel,
...here, let me help you...
Basically, the short answer is NO. You will have to get an XL-H1 camera to playback your 25F footage.
When the XL-H1 records it's progressive footage in the F format, it is recoding a no frills 24, 25 or 30 progressive frame every second at 1080 verticle lines of resolution. There is no pulldown and it is not over a 60i format like Sony. The reason your tape did not work with the Sony deck or camera is because Sony's method of recording the CF format in 24, 25 & 30 type of 1080 HDV is always over 60i. This is why the Canon XL-H1 can playback ALL TYPES of modes recorded by Sony HDV cameras with no problems, but Sony can only playback ONE TYPE of the Canon format, which is 60i.
24F, 25F & 30F needs to be played back using the XL-H1 camera, because there is no deck available as of date.
HOWEVER, THERE'S AN OPTION....
Canon has just released (and is now available) a consumer camera called the CANON HV10 which records HDV in 60i only. BUT, this camera will "playback" 24f, 25f or 30f recorded frootage with ease. Another nice feature the HV10 has is the ability to convert HD footage in realtime to "letterboxed" SD for viewing on a non HDTV.
So there you have it. Those are your options.
I hope that helps,
