Tested on the stock movie player, and also moboplayer. Both play the same way. They are downloads, but work perfectly if played on pc, until after the rip. The new mp4 after converting skips even while on the PC so it is pretty obvious there was an error in the conversion somewhere. No adjustments were made after selecting the XOOM HQ2 settings. I was maybe multi-tasking a little. But no more than just surfing the web. I tried 2 movies, first was Tron 1080p, and the second was How to Train A Dragon, also 1080p for my kiddo (And me I suppose. Freaking awesome kids movie!)sounds like a botched conversion.
did you test on another player on your xoom to see if it does the same thing? are these rips from disks you own? or are they downloads off the net?
did you make any adjustments to the stock settings in the program?
were you multitasking on the same computer that was also doing the conversions?
what movies?
When I get home from work I'll just try it again on the XOOM HQ1 settings and see whats up. It could be different. Is there a noticeable difference between HQ1 and HQ2 (besides the file size obviously) when viewing ripped movies on the xoom?
