[vdr] [PATCH] improve compatibility with old DD recordings

[s.huelswitt@gmx.de (Stefan Huelswitt)]

Hi,
I have a lot of older recording with DD which are not recognised
by vdr. The attached patch improves compatibility for me.

Technical: many of recordings doesn't have set the align bit even
that the data is actualy align. I take the pts/dts flags a second
best indicator for aligned data.

Regards.
