You can take the size of the index file, divide it by 8 and you get the number of frames in the recording. The info file tells you the number of frames per second (at least with newer TS recordings).
I don't think this calculation is always accurate (i.e. for h264/HD recordings) right now. For a 1080i recording the info file contains "F 25" (shouldn't it be 50 frames for 1080i50?)
Example (recorded with vdr 1.7.10): # ls -la insgesamt 7219260 drwxr-xr-x 2 vdr vdr 59 28. Nov 15:04 . drwxr-xr-x 3 vdr vdr 38 22. Nov 20:12 .. -rw-r--r-- 1 vdr vdr 7389603764 22. Nov 22:13 00001.ts -rw-r--r-- 1 vdr vdr 2901984 22. Nov 22:13 index -rw-r--r-- 1 vdr vdr 681 22. Nov 20:12 info
# grep "^F\ " info F 25
2901984 (size of the index file) / 8 = 362748 (frames) 362748 / 25 (framelength according to info) = 241min 49sec (wrong!) 362748 / 50 (real framelength) = 120min 54sec (actual length)
