Can't watch downloaded shows on IPad

I downloaded three shows to watch while traveling. All three appeared to download successfully.

However, at 4-8 minutes into each show, I get the following error, "Problem Playing Recording -- An unknown error occurred." I retry to watch and get about 3 seconds in and it fails again. I can move the slider across the entire show and can see that the entire show is there, but I can't actually watch it.

I checked and the shows on the TiVo box are intact and watchable.

I have 4 Premieres with the Stream device.

Any ideas?

Thanks,

John
