VOB playback virtually impossible on ATV Flash Black

Hi, I’m a long time ATV Flash user on the 1st Gen AppleTV. I’ve upgraded to Black and think I’m on latest version of everything. However VOB playback is awful (stutters every second).

I store all my DVDs in raw format (VOB) on a NAS. With my 1st Gen ATV I could play these with no problem via XBMC. I get the incessant stuttering problem when I do the same thing on Black.

I’m not hooked on using XBMC, and if you have suggestions for alternate apps that work, I’m all ears.

Thanks

Dan

FYI, I’m using SMB ton connect to my NAS (same connection I used on 1st Gen).
