I ran into this problem as well and I worked around it by hard-coding
the size in my script since I have my STB's outputting a single
resolution so I know they are always going to be 720p files. I know
it's not much help, but maybe some comfort that it's a problem.
I ran into this with the first version of the HDPVR firmware. I never
bothered checking after that since I'm still outputting only 720p files.
